Allocate IRQ to PCI VGA
When set to No, this parameter frees an IRQ which otherwise would have been allocated to
the PCI VGA card. The default is Yes.
PCI IDE Bus Mastering
When set to Disabled, this parameter deactivates the bus mastering capability of the PCI IDE
controller. The default setting is Enabled.
Use ESCD for PCI IRQ Assignment
If this parameter is set to Yes, when the system boots, it reads ESCD data to determine how
to assign IRQs to system devices and option cards. You can use PnP operating systems to
manipulate this ESCD data to assign specific IRQs to specific system devices and option
cards on subsequent system boots. When the parameter is set to No (default), you can use
the BIOS to assign IRQs to PCI devices regardless of ESCD instructions.
PCI Slot x IRQ Priority
Use this parameter to assign specific IRQs to specific PCI cards when ESCD data is not
being used. The default is Auto. Options are 3, 4, 5, 7, 10, 11, 12, 14, and 15.
DMA Channel x Usage
This parameter specifies whether a given DMA channel is to be reserved for an ISA card, or
is free to be assigned to another device by the PnP BIOS. The options are PnP (default) and
ISA.
IRQ x Usage
This parameter specifies whether a given IRQ is to be reserved for an ISA card, or is free to
be assigned to another device by the PnP BIOS. The options are PCI/PnP (default) and ISA.
ISA Reserved Memory Size
Use this parameter in conjunction with the ISA Reserved Memory Address parameter to
allocate a fixed amount of memory for ISA cards that require a specific amount of memory
and a set memory location. The memory size you select limits the memory addresses
available to assign to ISA cards. The default is Disabled.
ISA Reserved Memory Address
Use this parameter in conjunction with the ISA Reserved Memory Size parameter to allocate
a fixed amount of memory for ISA cards that require a specific amount of memory and a set
