This mainboard requires correct configuration information; otherwise, a malfunc -tion
may result.
Static electricity can cause serious damage to integrated circuit chips.
To avoid building up a static electric charging on your body, be sure
you discharge any static electricity by grounding yourself before
handling the chips. If chips are handed from one person to another,
they should touch hands first, then pass th e chips.

2 Memory Configurations
System Memory
TR5510 AIO uses SIMM (Single -In-line-Memory Module) for its system memory.
It accepts a minimum of 4MB and a maximum of 128MB memory size. There are
two memory banks which support 1/2/4/8/16/32/64 MB 72 -pin, single- and/or
double-density SIMMs.
DRAM insertion on every bank should come in pair and of the same
type (same size and same density). For instance, if you only have two
SIMM modules, you cannot install one module in socket SIMM1 and
another module of the same type on the SIMM3. Likewise, memory
type mixing is not allowed within a bank.
The DRAM type of SIMM1 & SIMM2 is independent of SIMM3 & SIMM4.
The following table lists some possible SIMM module combinations and the total
memory size of each com bination.

TR5510 AIO User’s Manual

Table 2 -1. System Memory Configurations
Cache Memory Subsystem
The TR5510 AIO supports standard SRAM and Pipelined Burst SRAM, but notice
that just one kind of the SRAM’s can be used on-board at one time. For example, if
the Pipelined Burst SRAM module have existed on the cache module slot (U24), you
should not to plug any standard SRAM on your mainboard.
The TR5510 AIO mainboard does not support the kind of Pipelined
Burst SRAM module without TAG RAM on it.
The table below lists the cache memory configurations.
: Users can use pure +3.3V SRAM or +3.3V/5V mixed mode SRAM as the
standard data SRAM. Using the wrong type of SRAM could cause severe
damage to the mainboard.

If user sets this option to “Disabled”, the “1st Available IRQ” ,“2nd
Available IRQ”, “3rd Av ailable IRQ” and “4th Available IRQ” options
below will not be shown on the screen.
Slot 1/2/3/4 Using INT# - defines the INTx# assigned to every PCI slot. The
available options are:
1st/2nd/3rd/4th Available IRQ - specifies the IRQ for the PCI devices. The end
user should assign an available IRQ if the PCI device needs an IRQ service The
available options are:
• 9 (3rd Available IRQ default)
• 10 (1st Available IRQ default)
• 11 (2nd Available IRQ default)
• 12 (4th Available IRQ default)
The “1st Available IRQ” ,“2nd Available IRQ”, “3rd Available IRQ” and
“4th Available IRQ” options above will not be shown on the screen untill
users set Disabled for the
PnP BIOS Auto - Config
setting.
PCI IDE Activied by - programs the PCI IRQ to single edge or logic level.
Level/Edge sensitivity is programmed per controller. Every IRQ input for a given
bank is either “Edge” (default) or “Level” triggered.
PCI IDE IRQ Map To - defines the on board IDE IRQ Routing either from the PCI
Bus or the ISA Bus. The available options are:
If user sets this options to “ISA”, both the “Primary IDE INT#” and
“Secondary IDE#” options below will not be shown on the screen.
Primary/Seco ndary IDE INT# - defines the primary/secondary IDE INT# of the
PCI IDE card. The available options are:
• A (default of Primary IDE INT#)
• B (default of Secondary IDE
INT#)

Load BIOS Defaults
In the event of a loss in memory on the configuration SETUP, the user can restore
the information on the BIOS by loading its default values. Loading the BIOS
defaults provides safe booting of the system.
This option may not be able to configure all the values within the
SETUP program according to the installed equipments (i.e., floppy
drives A: & B:, hard disk drives C: & D:).
Load Setup Defaults
SETUP defaults are considered default values with which the system will be enabled
to perform bette r. This is due to the enabling of some options within the SETUP
program. However, if problems are encountered after loading the SETUP defaults,
reboot the system and load the BIOS defaults instead.
Password Setting
The Password Setting utility allows you to set, change, and disable the password
stored in the BIOS. To change the password setting, press <Enter> on the Password
Setting option of the main menu and then type the new password.
The password can be at most 6 characters long. The program will re quire you to
confirm the new password before it exits and enables the utility. To disable the
password setting, press the <F1> once the program asks you to enter the new
password.
Configure the Security Option within the BIOS Features Setup
corresponding to the setting in this utility.
IDE HDD Auto Detection
The IDE HDD Auto Detection provides auto configuration of the hard drive installed
in the system. It supports LBA, Large, and Normal modes. If the system's hard disk
drive has a capaci ty of over 528MB and supports LBA functions, you may enable
either the LBA mode or the Large mode. On the other hand, if the hard disk drive's
capacity is over 528MB but does support LBA functions, you may enable the Large
mode in order to use over 528MB.

TR5510 AIO User’s Manual
4-13
a. The LBA and Large modes will only appear on the screen when the
installed hard disk drive is specified to support the LBA mode.
b. In the case when a hard disk drive's cylinder specification exceeds
1024, and does not support the LBA functions, only the Large mode
will be displayed on the screen.
c. With a hard disk drive supporting cylinders below 1024, only the
Normal mode will appear on the screen. The Normal mode will also
be shown on the screen under conditions a & b above.
d. Hard disk drives w ith less than 528MB total capacity must be set to
Normal mode when combined with either old BIOS versions or the
Award BIOS.
LBA and Large modes are new specifications which may not be fully
supported by all operating systems. An example of which is th e current
version of UNIX System (R3.2.4) which is still unable to support the LBA
function. Therefore, determine the specifications of your hard disk drive
and operating system before selecting the drive's mode.
After pressing the <Enter> key on this it em of the main menu, the display screen will
show the following screen.

Once the program detects the type of hard disk installed, it will display the relative
information such as the type, cylinders, heads, write pre -compensation, landing zone,
number of sectors per track, size and mode. A message asking you to accept the IDE
HDD detected will also be flashed on the screen.

Quitting SETUP
After making all modifi cations in the SETUP program, go to the option "Save & Exit
SETUP" then press the <Enter> key. The program will display the following screen.
Press <Y> to confirm the changes made, and the <N> or the <ESC> keys if further
modifications are still necessary before exiting the SETUP program. Once the <Y>
key is pressed, the system will automatically exit the program and reboot. However,
if you want to cancel all changes made under the SETUP program, go to the option
"Exit Without Saving".
Press <Y> and the system will exit the SETUP program then reboot without saving
