Award BIOS Setup Guide
31
A short description of the screen items follows:
PNP OS Installed: Set this option to Yes if the operating system installed in the computer is Plug
and Play-aware (e.g. Windows 95).
Resources Controlled By: The Award Plug and Play BIOS can automatically configure all the
boot and Plug and Play compatible device. If you select Auto, all the interrupt (IRQ) and DMA
assignment fields disappear, as the BIOS automatically assigns them.
Reset Configuration Data: If enable this option, the BIOS will clear and reset the ESCD after
hardware reset.
IRQ#/DMA# assigned to: These items will be shown only when “Resources Controlled By”
option is set the “Manual”. The available options are “Legacy ISA” and “PCI/ISA PnP”. If the
option is set to “Legacy ISA”, the BIOS will never assign the specified IRQ/DMA resource to
PCI or ISA PnP Devices. If “PCI/ISA PnP” is chosen, the BIOS will make the specified
IRQ/DMA have a chance to be assigned to the PCI or ISA PnP devices.
PCI IDE IRQ Map To: Choose PCI-AUTO, PCI-SLOT1, PCI-SLOT2, PCI-SLOT3, ISA. The
default setting is PCI-AUTO.
Primary/Secondary IDE INT#: Each PCI peripheral connection is capable of activating up to
four interrupts: INT#A, INT#B, INT#C and INT#D. By default, a PCI connection is assigned
INT#A. Assign INT#B has no meaning unless the peripheral device requires two interrupt
services them just one.
Used MEM Base Addr/Used MEM Length: These items will be shown only when “Resources
Controller By” option is set to “Manual”. They are used to reserve the memory space for the
memory installed on the ISA card in the specified memory segment (such as some network card).
The available options for “User Mem Base Addr” are “N/A”, “C800”, “CC00”, “D000”, “D400”,
“D800” and “DC00”, which is used to select the base memory address of the ISA card used. With
the “Used Mem Base Addr” is selected, the size of the memory installed on ISA card is chosen by
“Used Mem Length”: “8K”, “16K”, “32K” or “64K”
