ADVANCED CMOS SETUP
"ADVANCED CMOS SETUP" lists some system features that allows you to fine tune your system setup.
· Typematic Rate Programming
: Choose Enabled or Disabled. Enable this option to adjust the keystroke repeat rate.
Adjust the rate via Typematic Rate Delay and Typematic Rate.
· Typematic Rate Delay
: Choose the delay between holding down a key and when the character begins repeating.
Default is 500milliseconds.
· Typematic Rate
: Choose the rate a character keeps repeating. Default is 15 characters per second.
· Above 1MB Memory Test
: Default is "Disabled" to speed up power-on initialization process and the BIOS will only test
the extended memory every 32K locations only to determine the on-board memory size.
·
Memory Test Tick Sound
: Default is "Enabled" for the ticking sound during memory test.
·
Memory Parity Error Check
: Default is "Enabled" to test for transmission errors in data read from memory.
·
Hard Disk Type 47 RAM Area
: The BIOS uses this area to store extended information, such as user definable drive type
47.
There are two options:
Default option is
0:300
in lower system RAM
DOS 1KB
in the top 1KB of the 640KB DOS base memory
· System Boot Up NumLock
: When the computer boots, it selects the numeric values rather than the cursor control
functions on the numeric keypad of IBM compatible keyboards. Most extended compatible keyboards have separate
cursor control keys. It is therefore unnecessary to use the numeric keypad for this. The default setting is "On".
· Floppy Drive Seek At Boot
: Default is "Disabled". On this setting the system will check the hard disk first to find the
disk operating system. This option also allows the user to run the system without a floppy disk drive.
· System Boot-Up Sequence
: If "A:, C:" (default), the BIOS will look for bootable operating system files from floppy drive
A: first before looking for them in drive C:. You can reverse this sequence by selecting "C:, A:".
· Cache Memory
: Select "Both" to turn on both CPU internal cache and system board external cache.
· Password Checking Option
: Choose "Setup" or "Always". default setting is "Setup". The password feature can be
used to prevent unauthorized system boot-up or unauthorized use of BIOS SETUP.
"Always" Each time the system is turned on, the pass word prompt appears.
"Setup" If there is a password set, the Password prompt only appears if you attempt to enter the BIOS Setup
program. If there is no set password, the Password Checking Option is disabled. You create a password
by using "CHANGE PASSWORD" in the Main Menu.
· Video ROM Shadow C000/C4000, 32K
: Shadowing helps to speed up BIOS access by copying BIOS code to fast 32-bit
RAM area and executes it from there. The default setting is "Enabled".
· Adapter ROM Shadow
: Default setting is "Disabled". If you have other expansion cards with ROMs on them such as
SCSI controller, you will need to know which addresses the ROMs use.
·
Boot Sector Virus Protection
: Select 'Enabled' to protect the Boot sector of your hard disk from software virus such as
"Michael Angelo".
