4. BIOS SETUP

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]

Primary VGA BIOS [PCI Card]

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 graphics card. [AGP Card] uses the AGP card as your primary card. The default, [PCI Card], allows your PCI graphics card to take precedence when detected. Configuration options: [PCI Card] [AGP Card]

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]

PCI/PNP ISA IRQ Resource Exclusion

4. BIOS SETUP

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]
