Memory
The category is display-only which is determined by POST (Power On
Self Test) of the BIOS.
Base Memory
The POST of the BIOS will determine the amount of base (or conventional) memory installed in the system. The value of the base
memory is typically 512K for systems with 512K memory installed
on the mainboard, or 640K for systems with 640K or more memory
installed on the mainboard.
Extended Memory
The BIOS determines how much extended memory is present during the POST. This is the amount of memory located above 1MB in
the CPU's memory address map.
Expanded Memory
Expanded Memory is memory defined by the Lotus/Intel/
Microsoft(LIM) standard as EMS. Many standard DOS applications
can not utilize memory above 640K, the Expanded Memory
Specification(EMS) swaps memory which not utilized by DOS with
a section, or frame, so these applications can access all of the system
memory. Memory can be swapped by EMS is usually 64K within
1MB or memory above 1MB, depends on the chipset design.
Expanded memory device drive is required to use memory as Expanded Memory.
Other Memory
This refers to the memory located in the 640K to 1024K address
space. This is memory that can be used by different applications.
Dos uses this area to load device drivers to keep as much base
memory free for application programs. It is mostly use by the Shadow
RAM.

IDE HDD Auto Detection
The Enhanced IDE features was included in all 541 Award BIOS. Below is
a brief description of this feature.
1. Setup Change
( I ) Auto-Detection
BIOS setup will display all possible modes that supported by the
HDD including NORMAL, LBA & LARGE.
If HDD does not support LBA modes, no 'LBA' option will be shown.
If no of cylinders is less than or equal to 1024, no 'LARGE' option
will be show
Users can select a mode which is appropriate for them.
( II ) Standard CMOS Setup
CYLS HEADS PRECOMP LANDZONE SECTOR MODE
Drive C:User(516MB) 1120 16 65535 1119 59 NORMAL
Drive D:User(203MB) 684 16 65535 685 38 -----------
When HDD type is in 'user' type, the "MODE" option will be opened for user to
select their own HDD mode.

2. HDD Modes
The 541 Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE.
( I ) NORMAL mode
Generic access mode in which neither the BIOS nor the IDE controller will make any transformations during accessing.
The maximum number of cylinders, head & sectors for NORMAL
mode are 1024, 16 & 63
no. Cylinder (1024)
x no. Head ( 16)
x no. Sector ( 63)
x no. per sector ( 512)
528 Megabyte
If user set his HDD to NORMAL mode, the maximum accessible
HDD size will be 528 Megabytes even though its physical size may
be greater than that!
( II ) LBA (Logical Block Addressing) mode
A new HDD accessing method to overcome the 528 Megabytes
bottleneck. The number of cylinders, head & sectors shown in setup
may not be the number physically contained in the HDD.
During HDD accessing, the IDE controller will transform the logical address described by sector, head & cylinder number into its
own physical address inside the HDD.
The maximum HDD size supported by LBA mode is 8.4 Gigabytes
which is obtained by the following formula:
no. Cylinder (1024)
x no. Head ( 255)
x no. Sector ( 63)
x no. per sector ( 512)
8.4 Gigabyte

Page 72
( III ) LARGE mode
Extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinder without LBA
support. The 541 Award BIOS provides another alternative to support these kinds of HDD !
Example of LARGE mode
CYLS. HEADS SECTOR MODE
1120 16 59 NORMAL
560 32 59 LARGE
BIOS tricks DOS that the number of cylinders is less than 1024 by
dividing it by 2. At the same time, the number of heads is multiplied by 2. A reverse transformation process will be made inside
INT13h in order to access the right HDD address the right HDD
address!
Maximum HDD size
no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x no. per sector ( 512)
1 Gigabyte
If user set his HDD to NORMAL mode, the maximum accessible
HDD size will be 528 Megabytes even though its physical size may
be greater than that!
3. Remarks
To support LBA or LARGE mode of HDDs, there must be some
software involved. All these software are located in the Award HDD
Service Routine(INT 13h). It may be failed to access a HDD with
LBA (LARGE) mode selected if you are running under a Operating
System which replaces the whole INT 13h.

Error Beeps and Message
Error can occur during POST (Power On Self Test), which is performed
every time the system is powered on. Fatal errors are communicated
through a series of audible beeps. All errors except Beep Code 8 are fatal
errors. Fatal errors do not allow the system to continue the boot process.
Most displayed errors allow the system to continue the boot process.

Appendix BAward BIOS Reference
BIOS Reference - POST Message
When the BIOS encounters an error that requires that user to correct something, either a beep code will sound or a message will be displayed in a
box in the middle of the screen and the message "PRESS F1 TO CONTINUE,
CTRL-ALT-ESC OR DEL TO ENTER SETUP" will be shown in the information
box at the bottom.
POST Beep
Currently there are two kind of beep codes in BIOS.
The one code indicates that a video error has occurred and the BIOS can-
not initialize the video screen to display any additional information. This
beep code consists of a single long followed by three short beeps. The
other one code indicates that your DRAM error has occurred. This beep
code consists of a single long beep repeatedly.
: Video error
.......... : DRAM error
Error Message
One or more of the following messages may be displayed if the BIOS
detects an error during the POST. This list indicates the error messages for
all Award 541 BIOSes:
"CMOS BATTERY HAS FAILED"
CMOS battery is no longer functional. It should be replayed.
"CMOS CHECKSUM ERROR"
Checksum of CMOS is incorrect. This can indicate that CMOS become corrupt.
This error may have been caused by a weak battery. Check that battery and replace
if necessary.
