PCI VGA Palette Snoop

This item is for BIOS to snoop the appearance of VGA palette, and modify it when necessary.

PCI IDE BusMaster

When Enabled this option specifies that the IDE controller on the PCI local bus has bus mastering capability. PCI Slot1/2/3/4 IRQ Priority

The parameters of this item will set a interrupt signal to the PCI device fixed in the 1-4 PCI slot by priority.

DMA & IRQ

These options specify the bus that the named IRQs/DMAs lines are used on. These options allow you to specify IRQs/DMAs for use by legacy ISA adapter cards. These options determine if the BIOS should remove an IRQ/DMA from the pool of availability of IRQs/DMAs passed to the BIOS configurable devices. If more IRQs/DMAs must be removed from the pool, the end user can use these PCI/PnP Setup options to remove the IRQ/DMA by assigning the option to the ISA/EISA setting. The onboard I/O is configurable with BIOS.

Reserved Memory Size

This option specifies the size of the memory area reserved for legacy ISA adapter cards.

Reserved Memory Address

This option specifies the beginning address (in hex) of the reserved memory area. The specified ROM memory area is reserved for use by legacy ISA adapter cards.
