3.12.10 Plug and Play Configuration Subscreen
This section describes the options found on the Plug and Play configuration subscreen.
3.12.10.1 Configuration Mode
Sets how the BIOS gets information about ISA cards that do not have Plug and Play capabilities.
The options are Use Setup Utility and Use ICU (ISA Configuration Utility). The default is Use
Setup Utility.
If Use ICU is selected, the BIOS will depend on run-time software to ensure that there are no
conflicts between ISA boards with Plug and Play capabilities and those without. Only Boot With
PnP OS will be visible.
3.12.10.2 Boot with PnP OS
Enables the PC to boot with an operating system capable of managing Plug and Play add-in cards.
The options are None, Other, and Windows 95. The default is Windows 95.
3.12.10.3 ISA Shared Memory Size
Enables you to “unshadow” a block of the upper memory area. The options are Disabled, 16 KB,
32 KB, 48 KB, 64 KB, 80 KB, and 96 KB. The default is Disabled. If this is set to Disabled, the
ISA Shared Memory Base Address (described below) will not be visible.
Shadowing is a technique that copies a block of memory from an add-in card’s ROM to the same
address in system memory. This provides faster access and achieves higher performance. By
default, all upper memory is shadowed.
3.12.10.4 ISA Shared Memory Base Address
Sets the base address for the ISA Shared Memory. The options are C8000h, CC000h, D0000h,
D4000h, D8000h, and DC000h. The default is C8000h. This setting could affect the ISA Shared
Memory Size item. The value entered in the ISA Shared Memory Size item cannot extend to the
E0000h address. For example, if a size of 64K was selected, options D4000h, D8000h, and
DC000h will not be available.
3.12.10.5 IRQ 3, 4, 5, 7, 9, 10, 11, 12, 14, 15
Sets the status of the IRQ. The options are Available and Used By ISA Card. The default is
Available. The PCI auto-configuration code looks here to see if these interrupts are available for
use by a PCI add-in board. If an interrupt is available, the PCI auto-configuration code can assign
the interrupt to be used by the system. If your system contains an ISA agent that uses one of these
interrupts, select Used By ISA Card for that interrupt.
