Figure 4-6 PCI CONFIGURATION SETUP
PNP OS Installed : NO PCI IDE IRQ Map To : PCI-AUTO
Resources Controlled By : Manual Primary IDE INT# : A
Reset Configuration Data : Disabled Secondary IDE INT# : B
IRQ-3 assigned to : Legacy ISA
IRQ-4 assigned to : Legacy ISA
IRQ-5 assigned to : PCI/ISA PnP
IRQ-7 assigned to : PCI/ISA PnP
IRQ-9 assigned to : PCI/ISA PnP
IRQ-10 assigned to : PCI/ISA PnP
IRQ-11 assigned to : PCI/ISA PnP
IRQ-12 assigned to : PCI/ISA PnP
IRQ-14 assigned to : PCI/ISA PnP
IRQ-15 assigned to : PCI/ISA PnP
DMA-0 assigned to : PCI/ISA PnP
DMA-1 assigned to : PCI/ISA PnP
DMA-3 assigned to : PCI/ISA PnP
DMA-5 assigned to : PCI/ISA PnP
DMA-6 assigned to : PCI/ISA PnP
DMA-7 assigned to : PCI/ISA PnP
Reset Configuration Data:The default value is disabled.
Disabled:Normal Setting.
Enabled :If you had plugged some Legacuy cards in the system and recorded into
ESCD(Extended System Configuration Data), you can set this field to
enabled to clear ESCD.
PCI IDE IRQ Map To:The default value is PCI-AUTO.
When you have true PCI card(s) plugged into the system, you do not have
to change anything here in the SETUP program. However, if you do not
know whether you have true PCI card or not, please refer to your PCI card
user's manual for the details.
When you have a legacy card (describbed in section 2-6) to be plugged
into the system,a proper setting is extremely important or it may cause the
system hang. The diagram shown below tells you how the Rotating
Priority Mechanism is designed.
Resource Controlled By:The default value is Manual.
Manual :PNP Card's resources will be controlled manually. You can set which
IRQ-X and DMA-X are assigned to PCI/ISA PNP or Legacy ISA Cards.
Auto :If your ISA card and PCI card are all PNP cards, BIOS will assign the
interrupt resource automatically.
