Troubleshooting
There is also another way to prevent this detour. Go to “
Standard CMOS Setup
” and tune in
the hard disk status, the “
Primary Master
”, and “
Primary Slave
” to “
Auto
” with their “
32 bit
mode
“ being tuned to “
ON
”. This will force your system to automatically detect the current
attached hard disks during each boot-up sequence. It is then no longer necessary to manually
detect the hard disks each time the boot-up sequence is tried.
Note that loading the default optimal BIOS setting will not change the hard disk detection
status back to “
Auto
”. You may find that when you load the default BIOS setting, the hard disk
detection status remains unchanged.
Additionally, it is also recommended to double check the hard disk or CD-ROM setting in the
event of connecting two IDE devices through one IDE port. One of these two devices needs to
be configured as a slave device to prevent a detection failure of the IDE devices. There cannot
be two IDE devices configured as the master devices at the same time.
Improper Disable Operation
There are many occasions in BIOS Setup where users disable a certain device/feature in one
application, but do not enable it before manipulating another application where the disabled
device is needed. Users fail to detect this device/feature and end up with a system failure.
Please check the BIOS setting so that the devices or ports that you need are not disabled. These
include the floppy drive, COM1/COM2 ports, parallel port, USB ports, external cache, and
on-chip VGA display mode.
It is also very common that users would like to disable a certain device/port to release IRQ
resources. A few good examples are:
t
Disable COM1 serial port to release IRQ #4
t
Disable COM2 serial port to release IRQ #3
t
Disable parallel port to release IRQ #7
t
Disable PS/2 mouse to release IRQ #12
