WATCHDOG TIMER

The watchdog timer is a hardware timer which resets the processor
board if the timer is not refreshed by software periodically. The
timer is typically used to restart an application which becomes hung
on an external e ve nt. When the applic a tion is hung, it can no longer
refresh the t imer. The watchd og timer then times out and rese ts the
processor board.

The watchdog tim e r has two levels of enable. First, th e watc hdog
timer jumper must be moved to the "enabled" position, which puts
the watchdog timer under softwar e control. Second, use r-supplied
software must start the watchdog timer via Keyboard Controller
(8042) Port 2, bit 3 (P23). P23 is set high from reset. Set ti ng P23
low starts the wat ch dog timer timeout of 1.2 seconds (nom inal).
Before the end of the timeout , P23 must be toggled high then low to
restart the timeout. If P 23 is left low un til the end of th e t imeout, th e
watchdog timer issues a hardware reset to the processor board. The
timer should be refreshed by the software every 1.0 seconds to
prevent a timeout.

A set of watchdog timer software is available from Technical Sup­port. The software includes sample C code which can be embedded
in a user program and demo software to demonstrate and test the
watchdog timer.

EXTENDED INDUSTRY STANDARD ARCHITECTURE

EISA OVERVIEW

The Extended Industry Standard Architecture (EISA) is a superset of
the ISA 8-bit and 16-bit architecture. It extends the capabilities of
that standard while maintaining compatibility with ISA expansion
boards.

EISA introduces the major advances described below.

Compatibility with ISA

EISA systems maintain full compatibility with the existing industry
standard. EISA connectors are a superset of the 16-bit connectors on
ISA system boards. ISA 8-bit and 16-bit expansion boards can be in­stalled in EISA slots. All EISA performa nc e and f unc tion enhance­ments are superset features that maintain full compatibility with ISA
expansion boards and software.

Memory Capacity

EISA system s support a 32-bit ad dr es s pa th. ISA memory car ds c an
be used in the lowe r 16 me ga bytes without modification. EISA
memory cards can add as much memory as needed for the applica­tion. The tot al me mory supporte d is limited only by the packa ging
constraints of the individual product, not by the system architecture.

Synchronous Data Transfer Protocol

The EISA bus achieves its speed and flexibility through the use of a
synchronous tr an sf er protocol. Bus maste r s a nd multiple pro cessors
can synchronize their bus cycles to a common clock to achieve maxi­mum performa nc e. The sync hr onous transfer pro tocol also provides
the cycle control necessary to execute Burst cycles with up to 33MB
per second data transfers.

TECHNICAL REFERENCE 2-1

EISA REFERENCE

On the EISA synchronous bus, control signals, address lines and data
bus use a bus clock generated by the system board as the reference
for a transfer. Unlike many systems, however, the bus clock is not a
fixed freque ncy. Since the sy stem board is th e source of most bus
cycles, the system board adjusts the bus clock frequency and phase
to achieve the maximum performance of the CPU and memory.

EISA provides a variety of cycle types to cover the range of speed
and the comple xity requireme nts for different applications. The
standard transfer cycle requires two clock cycles, but CPU’s are per­mitted to generate a 1.5 clock compressed cycle for slaves that re­quest it. At the high end of the performance spectrum are Burst
cycles which require one clock per transfer.

Enhanced DMA Functions

EISA systems provide a number of DMA enhancements, including
32-bit addressability, 8-bit, 16-bit and 32-bit data transfers and
higher performanc e arbi tr a ti on a nd da ta transfer cycles. EISA DMA
provides ISA compatible modes, with ISA timing and function as the
default.

DMA offers a lower cost alternative to an intelligent bus master.
The EISA DMA functions are intended for I/O peripherals that do
not require local intelligence on the peripheral interface.

32-bit Address Support for DMA Transfers

EISA 32-bit address support enables ISA, as well as EISA, DMA
devices to tra n sfer data to any 32-bi t me mory address. The def au lt
DMA supports ISA compatible 24-bit address with no software or
hardware modifications. DMA softwar e can be modified to support
the 32-bit memory space without modifications to the DMA
hardware.

2-2 TECHNICAL REFERENCE

EISA REFERENCE

8-bit, 16-bit or 32-bit Data Transfers from DMA Devices

Any DMA channel can be programmed for 8-bit, 16-bit or 32-bit
data transfers. An 8-bit DMA device uses the low 8 bits of the data
bus, a 16-bit device uses the low 16 bits, and a 32-bit device uses the
full 32-bit data bus.

A 32-bit DMA device can perform up to 33MB per second data trans­fers using Burst cycles.

Performance Gains for DMA Devices

EISA DMA devices can be programmed for high-performance data
transfers usi ng one of fo ur DMA cy cle type s. The defa ul t c yc le type,
compatible cycles, delivers a higher data transfer rate than ISA com­patible computers. The improvement is the result of EISA’s faster
bus arbitration and requires no hardware or software modifications to
ISA compatible DMA devices. Type "A" and Type "B" cycles are
EISA modes that, with special programming, allow some ISA com­patible DMA devices to achieve even higher performance. The
Burst DMA (Type "C") cycle type is the highest performance DMA
cycle and is only available to DMA devices designed specifically for
Burst.

Bus Master Capabilities

EISA based computers support a bus master architecture for intel­ligent peri phe r al s. The bu s master architec ture provides a high ­speed data channel with data transfer rates up to 33MB per second
using EISA Burst cy cle s. The bus master pr ovi de s local intel lige nc e
by including a dedicated I/O processor and local memory. It can
relieve the burden on the main CPU by performing sophisticated
memory acce ss functions, such as no n- or de red sc a tt er-gather data
transfers. Example s of a pplications t ha t mi ght benefit from a bus
master implementation include communication gateways, disk con­trollers, LAN interfaces, data acquisition systems, and certain classes
of graphics controllers.

Data Size Translation

The EISA bus system provides a mechanism for EISA expansion
boards to comm uni cate with ISA compatible devices. The EISA bus
master or slave generates EISA data and control signals, letting the
system board copy the data to the appropriate byte lines and translate
the control signals as necessary.

The system board provides the automatic translation for 16-bit ISA
bus masters, 8-bit or 16-bit memory and I/O slaves, and DMA
devices. The system board also prov ide s a utomatic tra nslation for
transactions between 16-bit and 32-bit EISA devices.

Bus Arbitration

EISA systems also provide a centralized arbitration scheme that al­lows efficient bus sharing among multiple EISA bus masters and
DMA devices. The cent ral iz e d a rbitration support s pre em ption of an
active bus master or DMA device and can reset a device that does
not release the bus after preemption.

The EISA arbitration method grants the bus to DMA devices,
DRAM refresh, bus masters and CPU functions on a fair, rotational
basis. The rotational scheme pr ovides a short lat en cy for DMA
devices to assure com patibility with ISA DMA de vice s. Bus m aste rs
and the CPU, which typically have buffering available, have longer
but deterministic latencies.

Edge/Level Triggered Interrupts

EISA system s pr ovide level-triggered, share a ble interrupts. Any
EISA interrupt can be individually configured for level- or edge-trig­gered operation. Edge-triggered operation provides full com­patibili ty with existing interrupt-dri ve n I SA devices. Level-triggered
operation facilitates the sharing of a single system interrupt by a num­ber of devices. F or example, level-triggered inte rrupts might be use d
to share a single interrupt between a number of serial ports.

Automatic System Configuration

EISA provides the capabilities for automatic configuration of system
and expansion bo ards. EISA expansion boa rd manuf a ct ur e rs inc lude
configuration files with expa nsion board pro duc ts. The configura­tion files can be included with either new, fully programmable EISA
boards or switch- c onf igured ISA product s. The conf iguration file s
are used at system configuration time to assign system resources
(such as DMA channels, interrupt levels) and thus prevent conflicts
between the i nstalled expans ion boards. For switch-configurabl e
boards, the configuration files can be used to outline the proper as­signment of resources and instruct the user about the proper selection
of switch settings.

To accomplish the automatic system and expansion board configura­tion, EISA provides a method for accessing I/O port ranges that are
slot speci fic . Thi s me a ns that a board using these ranges can be
plugged into any slot in the system without the risk of I/O range con­flicts. These I/O range s c an be us ed for expa nsion board initia liza­tion or for normal I/O port assignments that are guaranteed not to
conflict with any other expansion board installed in the system.

EISA also includes a product identification mechanism for systems
and expansion board products. The pro duc t identifier al lows
products to be identified during the configuration and initialization
sequences for the system and expansion boards. EISA includ es
guidelines f or sel e ct ion of a product identifier. The identifier of each
product is selected by the product manufacturer and does not need
the approval of any other party in the industry.

EISA BUS PIN NUMBERING AND ASSIGNMENTS

The EISA (P1/P2) 188-pin connector is a single unit and in ap­pearance resembles the existing ISA connector. The difference be­tween the ISA connector and the EISA connector is a second level of
contacts in the EISA connector. The ISA contacts are the upper row
(A, B, C and D); the EISA contacts are the lower row (E, F, G and
H). The EISA (P1/P2) conne c tor pinout is the standar d pinout as
specified in the EISA Specification.

ISA expansion boards can only be inserted into the EISA connector
far enough to make contact with the upper row of contacts (ISA con­tacts). Stops, or "access keys," are molded into the EISA connector
to prevent an ISA card edge from making contact with the EISA con­tacts. An EISA expansion board’s card edge connector goes deeper
into the connector and makes contact with the second row of contacts
(EISA contacts). EISA expansion boards are notched to a ll ow the
card edge to be pushed further into the connector and use the addi­tional contacts.

The PCXI Extension (P3/P4) 86-pin connector is an extension of the
standard EISA connector. This connector contains the same charac­teristics as the standard EISA connector. P3 is reserved for future
development and P4 is used to provide a passive backplane system
with the needed slot-specific and miscellaneous signals.

The pin numbering and assignments for the EISA 188-pin connector
are shown on the following pages. A # symbol at the end of a signal
name indicates that the active state occurs when the signal is at a low
voltage. When the # symbol i s ab se nt, the signal is a ct ive at a high
voltage.

EISA BUS SIGNAL DESCRIPTIONS

The following are descriptions of the signals from each connector of
the EISA Bus. They are separated into four categories:

• Address and Data Bus Signal Group

• Data Transfer Control Signal Group

• Bus Arbitration Signal Group

• Utility Signal Group

ADDRESS AND DATA BUS SIGNAL GROUP

The signals described in this section are used for memory and I/O ad­dressing and for the tr a nsf e r of da ta . Th es e signa ls are a combina­tion of new EISA signals and existing ISA signals.

AENx (ISA)

When negated (low), this slot-specific signal indicates that an I/O slave may
respond to ad dress es and I/O c omman ds on t he bu s. The "x " ref ers to the sl ot
number. AENx is also used to disable I/O accesses to all other option slots
during accesses to a particular slot’s slot-specific I/O address range.

BE#[3::0] (EISA)

BE#[3::0] are the byte enable signals that identify the specific bytes addressed
in a dwo rd. BE #[3 ::0 ] are pipe lin ed fr om o ne cy cle to the next an d mus t be
latched by the addressed slave if required for the whole cycle.

D[7: :0] (ISA)

D[7::0] are the low 8 bits of the data bus. 8-bit devices use these lines to
transf er dat a. A 1 6-bi t devi ce us es thes e li nes to trans fer t he lo w hal f of a word
when the addre ss lin e SA 0 is low o r w he n B E2 # or BE0# is as serted. 3 2- b it
devices use D[7::0] to transfer the first (lowest) byte of a dword when the
address line BE0# is asserted.

D[15::8] (ISA)

D[15::8] are the high 8 bits of the 16-bit data bus. 16-bit devices use these
lines to transfer the high half of a word when SBHE#, BE3# or BE1# is asserted.
32-bit devices use D[15::8] to transfer the second (third highest) byte of a dword
when the address line BE1# is asserted.

TECHNICAL REFERENCE 2-11

EISA REFERENCE

D[23::16] (EI S A)

D[23::16] are the second highest-order 8 bits of the 32-bit EISA data bus. A
32-bit device uses D[23::16] to transfer the third (second highest) byte of a
dword when the address line BE2# is asserted.

D[31::24] (EI S A)

D[31::24] are the highest-order 8 bits of the 32-bit EISA data bus. A 32-bit
device uses D[31::24] to transfer the fourth (highest) byte of a dword when the
address line BE3# is asserted.

LA[16::2] (EISA)

The LA[16::2] are a part of the l atchabl e address bus. T he latc hable ad dress
lines (LA[31::2]) are pipelined from one cycle to the next and must be latched
by the addressed slave if required for the whole cycle.

LA[23::17] (ISA )

LA[23: :17] ar e a part of th e 32-bi t latc habl e addre ss bus . They have t he same
characteristics as LA[16::2], except that they are wired to the 16-bit portion of
the ISA connector. An ISA slave can latch LA[23::17] with the trailing edge of
BALE.

LA#[31::24 ] ( EISA)

LA#[31::24] are the highest-order 8 bits of the 32-bit latchable address line.
They have the same characteristics as LA[16::2], except that they use inverted
logic.

SA[19::0] (ISA)

The SA[ 19 :: 0 ] lines a dd r es s m em o r y o r I/O de vices within th e s ys tem . T hey
form the low-order 20 bits of the 32-bit address.

SBHE# (ISA)

SBHE# (System Bus High Enable) indicates, when low, that expansion boards
that support 16-bit data transfers should drive data on the high half of the
D[15::0] data bus.

DATA TRANSFER CONTROL SIGNAL GROUP

The signals described in this section are used to control data transfer
cycles on the 8-bit, 16-bit and 32-bit bus. These signals are a com­bination of new EISA signals and existing ISA signals.

transferring 16 bits of data at once.

M-IO (EISA)

The main CPU or an EISA bus master asserts M-IO to indicate the type cycle
in progress as a memory cycle (high) or I/O cycle (low). M-IO is pipelined from
one cycle to the next and is latched by the addressed slave if needed for the
whole cycle.

MRDC# (ISA)

The system board or ISA bus master asserts MRDC# to indicate that the
addressed ISA memory slave should drive its data onto the memory bus.

MSBURST (EISA)

Bus master asserts MSBURST# to indicate to the burstable slave that the bus
master will execute Burst cycles.

MWTC# (ISA)

The system board or ISA bus master asserts MWTC# to indicate that the
addressed ISA memory slave may latch data from the memory bus.

NOWS# (ISA)

An ISA memory slave asserts NOWS# (No Wait State) after its address and
a command have been decoded to indicate that the remaining clock cycles are
not required.

SLBURST# (EISA)

A slave (typically, main memory) indicates its support of Burst cycles by
asserting SLBURST#.

SMRDC# (ISA)

The system board asserts SMRDC# to indicate that the addressed memory
slave should drive its data onto the memory bus.

SMWTC# (ISA)

The system board asserts SMWTC# to indicate that the addressed memory
slave may latch data from the memory bus.

2-14 TECHNICAL REFERENCE

EISA REFERENCE

START# (EISA)

The STAR T# s ignal pr ov id es timing cont rol at the s tar t of a cycle. The CP U
or bus master asserts START# after LA[31::2] and M-IO become valid.

W-R (EISA)

The status signal, W-R, identifies the cycle as a write (high) or read (low).

BUS ARBITRATION SIGNAL GROUP

The signals described in this section are used to arbitrate for bus con­trol. These signals are a combination of new EISA signals and exist­ing ISA signals.

DAK[7::5]#, DAK[3::0]# (ISA)

The system board asserts a DMA channel’s DAKx# to indicate that the channel
has bee n granted the bus. DAKx# can also be used to ackn owledge grant of
bus access to a 16-bit ISA bus master.

DRQ[7::5], DRQ[3::0] (ISA)

The DRQ[7::5] and DRQ[3::0] lines are used to request a DMA service from
the DMA subsystem or for a 16-bit ISA bus master to request access to the
system bus.

MAKx# (EISA)

MAKx# is a slot-specific signal that is asserted by the system board to grant
bus access to an EISA bus master. The "x" refers to the slot number.

Master16# (ISA)

A bus master asserts Master16# to indicate 16-bit data size.

MREQx# (EISA)

T-C to indicate that a DMA channel’s word count has reached terminal count.
In the input mode, T-C can be used by a DMA slave to stop a DMA transfer.

UTILITY SIGNAL GROUP

This section describes a variet y of ge ne ral utility signals. These sig­nals are all on the ISA connector.

IOCHK# (ISA)

An EISA or ISA expansion board can assert IOCHK# to signal the main CPU
that a serious error has occurred. Assertion of IOCHK# causes an NMI if
Port 0 61H bi t 3 is a "0" and NM I’s are en able d. P arit y err ors a nd un corr ectab le
system errors exemplify problems which might cause an expansion board to
assert IOCHK#.

IRQ[15::14], IRQ[12::9], IRQ[7::3] (ISA)

The IRQx lines are used to interrupt the CPU to request some service.

OSC (ISA)

OSC is a clock for use in timing applications. Its frequency is 14.31818MHz
with a 50 per cent duty cycle.

RESDRV (ISA)

Assertion of RESDRV causes a hardware reset of ISA and EISA expansion
boards. RESDRV is asserted by the reset controller during power up or after
a bus timeout. So ftware can cause asser tion of RESDRV by setting I/O
port 0461H bit 0 to a "1".

Sections 3 through 7 of this manual describe the operation of the
AMI WinBIOS and WinBIOS Setup. Refer to Running WinBIOS
Setup later in this section for standard Setup screens, options and
defaults.

When the system is powered on, WinBIOS performs the Power-On
Self Test (POST) rou ti ne s. These routines are divide d into two
phases:

1) System Test and Initialization. Test and initialize system

boards for normal operations.

2) System Configuration Verification. Compare defined c on-

figuration with hardware actually installed.

If an error is encountered during the diagnostic tests, the error is
reported in one of two different ways. If the error occurs before the
display d ev ic e is initialized, a seri e s of b eeps is transmitted. If the
error occurs after the display device is initialized, the error message
is displaye d on the screen. See BIO S Errors later in this section for
more information on error handling.

The following are the Power-On Self Tests (POST’s) which are per­formed when the system is powered on:

• Processor Register Test

• ROM BIOS Checksum Check

• Keyboard Controller Test

• CMOS Shutdown Register Test

• Channel 2, 1, 0 Timer Test

• Memory Refresh Test

• Base 64KB RAM Test

• CMOS Battery, Options Set, Checksum Check

• Display Type Verification

TECHNICAL REFERENCE 3-1

SYSTEM BIOS

• Entering Protected Mode

• Address Line Test and Memory Size Finding

• Conventional and Extended Memory Test

• DMA Controller Test

• Keyboard Test

• System Configuration Verification and Setup

NOTE: When you perform a warm boot by pr e ssing
<Ctrl><Alt><Del>, all memory tests are bypassed.

WinBIOS checks all system and cache memory and reports them on
both the initial WinBIOS screen and the WinBIOS System Con­figuration scre e n whic h a ppe a r s after POST is compl e te d. Wi nBIO S
attempts to initialize the peripheral devices by verifying the validity
of the system setup informati on stored in the syste m CMOS RAM.
(See the Running WinBIOS Setup section of this manual.) If
WinBIOS detects a fault, the screen displays the error condition(s)
which has/have been detected. If no errors are detected, WinBIOS at­tempts to load the system from any bootable device, such as a floppy
disk or hard disk.

Normally, the only POST routine visible on the screen is the memory
test. The foll owi ng screen displays whe n the system is power e d on:

SYSTEM BIOS

You have two options:

• Press <Del> to access the WinBIOS Setup program.

This option allows you to change various system parameters
such as date and time, disk drives, etc. The Running
WinBIOS Setup section of this manual describes the options
available.

You may be requested to enter a password before gaining ac­cess to the WinBIOS Setup program. (See Passw ord Ent ry
later in this section.)

If you enter the correct password or no password is required,
the WinBIOS Setup Main Me nu displays. (See Running
WinBIOS Setup later in this section.)

• Allow the bootup process to continue without invoking the

WinBIOS Setup program.

In this case, after WinBIOS loads the system, you may be re­quested to enter a password. (See Password Entry later in
this section.)

Once the POST routines complete successfully, a screen displays
showing the current configuration of your system, including proces­sor type, base and extended memory amounts, floppy and hard drive
types, display type and peripheral ports.

In systems with more than 1MB, WinBIOS reports 384KB less
RAM than it finds, because it accounts for the address space between
640K and 1024K which is unavailable to DOS . This spa c e i s use d
for video RAM, video BIOS, system BIOS and adapter ROM’s.

Password Entry

The system may be configured so that the user is required to enter a
password each time the system boots or whenever an attempt is
made to enter WinBIOS Setup. The password function may also be
disabled so that the password prompt does not appear under any cir­cumstances.

TECHNICAL REFERENCE 3-3

SYSTEM BIOS

The Password Checking option in the Advanced Setup program al­lows you to spec if y whe n the password promp t displays: Always or
only when Setup is attempt ed . The pa sswor d m ay be cha nge d using
the Password icon in the Security window of the WinBIOS Setup
Main Menu. If the password is null, the password prom pt does not
display at any time. A more detailed description of the password
setup function may be found under SECURITY in the Running
WinBIOS Setup section of this manual.

When password checking is enabled, the following password prompt
displays:

Enter CURRENT Password:

Type the password and press <Enter>.

NOTE: The null password is th e sy stem def ault and is in eff ect if a

password has not be e n assigned or if the CM OS is corrupted. In thi s
case, the pass wor d pr ompt does not display. To set up a passwo rd ,
you may use the Password icon in the Security window of the
WinBIOS Setup Main Menu. (See the Running WinBIOS Setup sec­tion of this manual.)

If an incorrect password is entered, the following screen displays:

Enter CURRENT Password: X
Enter CURRENT Password:

3-4 TECHNICAL REFERENCE

SYSTEM BIOS

You may try again to ent e r the corr e ct pa sswor d. If you enter the
password incorrectly three times, the system responds in one of two
different ways, depending on the value specified in the Password
Checking option on the Advanced Setup screen:

1) If the Password Checking option is set to Setup, the system

does not let you enter Setup, but does continue the booting
process. You mus t r eb oot the system manu al ly to retry enter ­ing the password.

2) If the Password Checking option is set to Always, the system

locks and you m ust reboot. After rebooting, you wil l be re­quested to enter the password.

Once the password has been entered correctly, you are allowed to
continue.

BIOS Errors

If an error is encountered during the diagnostic checks performed
when the system is powered on, the error is reported in one of two
different ways:

1) If the error occurs before the display device is initialized, a
series of beeps is transmitted.

2) If the error occurs after the display device is initialized, the
screen displays the error message. In the case of a non-fatal
error, a prompt to press the <F1> key may also appear on the
screen.

Explanations of the beep codes and BIOS error messages may be
found in Appendix A - BIOS Messages.

As the POST routines are performed, test codes are presented on
Port 80H. These codes may be helpful as a diagnostic tool and are
listed in Appendix A - BIOS Messages.

RUNNING WINBIOS SETUP

WinBIOS Setup keeps a record of the system parameters, such as
date and time , disk drives, and memory opt ions. The Setup
parameters reside in the Read Only Memory Basic Input/Output Sys­tem (ROM BIOS) so that they are available each time the system is
turned on . Win BI O S Se tup stores the information in the com ple men­tary metal oxide semiconductor (CMOS) m emo r y. When the system
is turned off, a backup battery retains system parameters in the
CMOS memory.

Each time the system is powered on, it is configured with these
values, unle ss the CMOS has been co rrupted or is fault y. The
WinBIOS Setup program is resident in the ROM BIOS (Read Only
Memory Basic Input/Output System) so that it is available each time
the computer is turned on. If, for some reason, the CMOS becomes
corrupted, the system is configured with the default values stored in
this ROM file.

As soon as the system is turned on, the power-on diagnostic routines
check memory, attempt to prepare peripheral devices for action, and
offer you the option of pressing <Del> to run WinBIOS Setup.

If certain non-fatal errors occur during the Power-On Self Test
(POST) routines which are run when the system is turned on, you
may be prompted to run WinBIOS Setup by pressing <F1>.

When selecting a certain setting for one WinBIOS Setup option
determines the available selections for one or more other WinBIOS
Setup opti ons, W inB I O S do es not pe r mit you to use the se settings
unless the setting for the fi r st option is changed. For example, the
Serial Port1 and Serial Port2 options in Peripheral Setup can be set to
2F8H, 3F8H, 2E8H or 3E 8H. If 2F8 H is sele c te d f or Seria l Port1,
WinBIOS disables 2F8H as an option for Serial Por t2. In va lid op­tions are grayed on the WinBIOS Setup screen and cannot be
selected.

DetectMaster/DetectSlave

The DetectMaster and DetectSlave options allow you to have
WinBIOS automatically detect the type of hard disk drive(s) in your
system. The automatic detecti on f unc tions only if you ha ve I DE
drives. The parameters are reported to the appropriate screen in
WinBIOS Standard Setup (Master Disk or Slave Disk), so the hard
drive can easily be configured.

If you select the DetectMaster or the DetectSlave icon from the
Utility window of the WinBIOS Setup Main Menu, the following
window displays:

WinBIOS searches for the hard disk, and if it can access the drive it
reads the disk parameters. It then searches the WinBIOS drive table
for matching parameters to determine the disk type and displays both
the type and pa ram et e rs on the screen. If no matching parameters
are found in the table, WinBIOS specifies the type as "USER" and
fills in the parameter val ue s it found on the dr ive . If it cannot access
the drive or if it is not an IDE drive, WinBIOS times out and
specifies that the disk drive is "Not Detected."

The screen displays the parameters for the disk drive and asks if you
accept the values:

TECHNICAL REFERENCE 3-15

SYSTEM BIOS

NOTE: The auto dete c t feature displays di sk parameter value s a s es ­tablishe d by the drive manufacturer. If the drive has been forma tted
using any other values, accepting the auto detect values will cause
erratic behavior. You must either reformat the drive to meet the
manufacturer’s specifications or use Standard Setup to enter para­meters which match the current format of the drive.

You have two options for each disk drive:

• Select No if you do not want to accept the hard disk type and

its associated parameters or if it is "Not Detected." You may
use Standard Setup to set up the correct parameters for the

The window above displays the message "Enter New Password."
This is the message you will see before you have established a new
password, or if the last password entered was the null password.

The message shown in the Password window changes depending on
where you are in the password procedure.

NOTE: The null password is the system default and will be in effect
if a password has not been assigned or if the CMOS has been cor­rupted. In this c as e, the "Enter CURRENT Pas swor d" prompt is
bypassed when you boot the system, and you must establish a new
password.

Type is the numeric designation for a drive with certain iden­tification parameters.

4-4 TECHNICAL REFERENCE

STANDARD SETUP

Cylinders (Cyl) is the number of disk cylinders found in the
specified drive type.

Heads (Hd) is the number of disk heads found in the specified
drive type.

Write Precompensation (WP) is the read delay circuitry which
takes into account the timing differences between the inner and
outer edges of the surface of the disk. The size of the sector gets
progressively smaller as the track diameter diminishes. Yet each
sector must st ill hold 512 bytes. Write precompe nsation cir­cuitry on the hard disk compensates for the physical difference
in sector size by boosting the write current for sectors on inner
tracks. This parameter designates the track (cylinder) number
where write precompensation begins.

Landing Zone (LZ) is the disk cylinder where the head lands.
This number determines the cylinder location where the heads
will normally park when the system is shut down.

Sectors (Sec) designates the number of disk sectors per track.

Size is the formatted capacity of the drive (in megabytes) based

on the following formula:

# of heads x # of cylinders x # of sects/cyln x 512 byte s/sect

Wait For "F1" If Any Error

Before the system boots up, WinBIOS executes the Power-On Self
Test (POST) routines, a series of system diagnostic routines. If any
of these tests fail but the system can still function, a non-fatal error
has occurred. Wi nB IOS r es ponds with an appropr ia te e rror me ssage
followed by:

Press F1 to RESUME

If this option is disabled, a non-fatal error does not generate the
"Press F1 to RESUME" message. WinBI OS still displ ays the ap­propriate error message, but continues the booting process without
waiting for the <F1> key to be pres se d. This e liminates the nee d f or
any user response to a non-fatal error con dition message . Non- fatal

Video or Adaptor Shadow

ROM shadow is a technique in which BIOS code is copied from
slower ROM to faster RAM. The BIOS is then executed from the
RAM.

Each option allows for a segment of 16KB or 32KB to be shadowed
from ROM to RAM. If one of these options is enabled and there is
BIOS code present in that particular segment, the BIOS is shadowed.

ISA Video Shadow

Video BIOS shad owing may be done in a 32K segment at C000H.
Enabling shadowing can speed up the operation of a machine be­cause RAM can be accessed more rapidly than ROM and the data
bus is wider to RAM.

The Setup screen displays the system option:

ISAVideo Shadow C000,32K : Enabled

Available options are:
