BIOS FEATURES SETUP
"BIOS FEATURES SETUP" lists some system features that allows you to
fine tune your system setup.
· Virus Warning
: Select "Enabled" to protect the Boot sector of your
hard disk from software virus such as "Michael Angelo".
· CPU Internal Cache
: Select "Enabled" to enable the cache memory
inside the 486 CPU chip.
· External Cache
: Select "Enabled" to enable external on-board cache
memory.
·
Boot 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".
· Swap Floppy Drive
: If this option is enabled, floppy drive A: will
become floppy drive B: and vice versa.
· Boot Up Floppy Seek
: Normally select "Enabled".
· Boot Up NumLock Status
: 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".
· IDE HDD Block Mode Transfer
: Some latest IDE hard disks support
multiple sector (Block Mode) transfer for faster performance. Users
select "Enabled" to take advantage of this feature.
·
Memory Parity Error Check
: Default is "Enabled" to test for
transmission errors in data read from memory.
· Security Option
: Choose "Setup" or "System". Default setting is
"Setup". The password feature can be used to prevent unauthorized
system boot-up or unauthorized use of BIOS SETUP.
"System" Each time the system is turned on, the pass word prompt
appears.
