Power-On Options
(continued)
Allows you to set:
(continued)
• Option ROM Prompt (enable/disable)
Enabling this feature will cause the system
to display a message before loading
option ROMs. (This feature is supported
on some models only.)
• POST Delay (in seconds) (None, 5, 10
15, or 20). Enabling this feature will add
a user-specified delay to the POST
process. This delay is sometimes needed
for hard disks on some PCI cards that spin
up very slowly; so slowly that they are not
ready to boot by the time POST is
finished. The POST delay also gives you
more time to select
F10
to enter
Computer (F10) Setup.
• I/O APIC Mode (enable/disable).
Enabling this feature will allow Microsoft
Windows Operating Systems to run
optimally. This feature must be disabled
for certain non-Microsoft Operating
Systems to work properly.
• ACPI/USB Buffers @ Top of Memory
(enable/disable). Enabling this feature
places USB memory buffers at the top
of memory. The advantage is that
some amount of memory below 1 MB is
freed up for use by option ROMs. The
disadvantage is that a popular memory
manager, HIMEM.SYS, does not work
properly when USB buffers are at top of
memory AND the system has 64 MB or
less of RAM.
