Disabled
Optional shadow is disabled
Note: 1. for C8000-DFFFF option-ROM on PCI BIOS , BIOS will
automatically
enable the shadow RAM. User does not have to
select the item.
2. IDE second channel control:
Enable : enable secondary IDE port and BIOS will assign IRQ15
for this
port.
Disable: disable secondary IDE port and IRQ15 is available for
other
device.
The item is optional only for PCI BIOS.
3. Some of the sound cards have an onboard CD-ROM controller
which uses IDE Secondary Port. In order to avoid PCI
IDE conflict,
the IDE secondary channel control has to select
“disable” then CD-
ROM can work.
