4. BIOS SETUP
PCI Configuration
USB IRQ [Enabled]
[Enabled] reserves an IRQ# for the USB to work. [Disabled] does not allow
the USB to have an IRQ# and therefore prevents the USB from functioning.
If you are not using any USB devices, you may set this feature to [Disabled]
to save an extra IRQ# for expansion cards. Configuration options: [Dis-
abled] [Enabled]
VGA BIOS Sequence [AGP/PCI]
If your computer has both PCI and AGP VGA cards, this field allows you to
select which of the cards will act as your primary card. [PCI/AGP] allows
your PCI card to take precedent when detected. [AGP/PCI] uses the AGP
card as your primary card. Configuration options: [PCI/AGP] [AGP/PCI]
Onboard ATA Device First [Yes]
Setting this field to [Yes] gives priority to UltraDMA/66 devices connected
to the onboard UltraDMA/66 IDE connectors over SCSI devices connected
to PCI interface SCSI cards (see also Other Boot Device in 4.6 Boot Menu).
Configuration options: [Yes] [No]
IRQ XX Used By ISA [No/ICU]
These fields indicate whether or not the displayed IRQ for each field is
being used by a legacy (non-PnP) ISA card. The default value indicates
either that the displayed IRQ is not used or that ISA Configuration Utility
(ICU) is being used to determine if an ISA card is using that IRQ. If you
install a legacy ISA card that requires a unique IRQ and you are not using an
ICU, you must set the field for that IRQ to [Yes]. For example: If you
install a legacy ISA card that requires IRQ 10, then set IRQ10 Used By ISA
to [Yes]. Configuration options: [No/ICU] [Yes]
PCI/PNP ISA IRQ Resource Exclusion
