Try Other Boot Devices
Setting the option to Yes allows the system to try to boot from other
devices if the system fails to boot from the 1st/2nd/3rd boot device.
S.M.A.R.T. for Hard Disks
This allows you to activate the S.M.A.R.T. (Self-Monitoring Analysis & Re-
porting Technology) capability for the hard disks. S.M.A.R.T is a utility that
monitors your disk status to predict hard disk failure. This gives you an op-
portunity to move data from a hard disk that is going to fail to a safe place
before the hard disk becomes offline. Settings: Enabled, Disabled.
BootUp Num-Lock
This item is to set the Num Lock status when the system is powered on. Set-
ting to On will turn on the Num Lock key when the system is powered on.
Setting to Off will allow end users to use the arrow keys on the numeric keypad.
Setting options: On, Off.
Floppy Drive Swap
Setting to Enabled will swap floppy drives A: and B:.
Floppy Drive Seek
This setting causes the BIOS to search for floppy disk drives at boot time.
When enabled, the BIOS will activate the floppy disk drives during the boot
process: the drive activity light will come on and the head will move back and
forth once. First A: will be done and then B: if it exists.  Setting options:
Disabled, Enabled.
MSI Reminds You...
1. Available settings for “1st/2nd/3rd Boot Device” vary de-
pending on the bootable devices you have installed.  For
example, if you did not install a floppy drive, the setting “Floppy”
does not show up.
2. If you want to boot from any of the USB-interfaced devices,
please set USB Legacy Support to All Device.

BIOS Setup
Primary Display
This configures the primary subsystem in the computer.  Available options:
Mono (monochrome), CGA40x25, CGA80x25, VGA/EGA, Absent.
Password Check
This specifies the type of AMIBIOS password protection that is implemented.
Setting options are described below.
Boot To OS/2
This allows you to run the OS/2
® operating system with DRAM larger than
64MB.  When you choose No, you cannot run  the OS/2® operating system
with DRAM larger than 64MB.  But it is possible if you choose Yes.
Internal Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system transfers
the requested data from the main DRAM into cache memory, for even faster
access by the CPU. The setting controls the internal cache (also known as L1
or level 1 cache). Setting to Enabled will speed up the system performance.
System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-
FFFFFh, resulting in better system performance. However, if any program
writes to this memory area, a system error may result. Setting options: Enabled,
Disabled.
C000, 32k Shadow
This item specifies how the contents of the adapter ROM named in the item
are handled. Settings are described below:
Option Description
Setup The password prompt appears only when end users try to
run Setup.
Always A password prompt appears every time when the com-
puter is powered on or when end users try to run Setup.

APIC Function
This field is used to enable or disable the APIC (Advanced Programmable
Interrupt Controller). Due to compliance to PC2001 design guide, the system
is able to run in APIC mode. Enabling APIC mode will expand available
IRQs resources for the system. Settings: Enabled, Disabled.
MPS Table Version
This field allows you to select which MPS (Multi-Processor Specification)
version to be used for the operating system. You need to select the MPS ver-
sion supported by your operating system. To find out which version to use,
consult the vendor of your operating system. Settings: 1.4, 1.1. Option Description
Disabled The specified ROM is not copied to RAM.
Enabled The contents of specified ROM are copied to RAM
for faster system performance.
Cached The contents of specified ROM are not only copied
to RAM, the contents of the ROM area can be writ-
ten to and read from cache memory.

SDRAM Frequency, SDRAM CAS# Latency, Row Precharge Time, RAS
Pulse Width, RAS to CAS Delay and SDRAM Bank Interleave auto-
matically to be determined by BIOS based on the configurations on the
SPD.  Selecting User allows users to configure these fields manually.
SDRAM Frequency
Use this item to configure the clock frequency of the installed SDRAM.
Settings options: 200MHz, 266MHz, 333MHz, 400MHz*, Auto.
*See Glossary: Recommended DDR400 Modules for details.
SDRAM CAS# Latency
This controls the timing delay (in clock cycles) before SDRAM starts
a read command after receiving it.  Settings: Auto, 1.5, 2, 2.5, 3 (clocks).
1.5 (clocks) increases the system performance the most while 3 (clocks)
provides the most stable performance.
Row Precharge Time
This item controls the number of cycles for Row Address Strobe (RAS)
to be allowed to precharge.  If insufficient time is allowed for the RAS
to accumulate its charge before DRAM refresh, refresh may be in-
complete and DRAM may fail to retain data.  This item applies only
when synchronous DRAM is installed in the system.  Available
settings: 2T, 3T, 4T, 5T.
RAS Pulse Width
This setting allows you to select the number of clock cycles allotted
for the RAS pulse width, according to DRAM specifications.  The
less the clock cycles, the faster the DRAM performance.  Settings: 6T,
7T, 8T, 9T.
RAS to CAS Delay
When DRAM is refreshed, both rows and columns are addressed
separately. This setup item allows you to determine the timing of the
transition from RAS (row address strobe) to  CAS (column address
strobe). The less the clock cycles, the faster the DRAM performance.
Setting options: 2T, 3T, 4T, 5T.
Bank Interleave
This field selects 2-bank or 4-bank interleave for the installed SDRAM.
