Boot to PnP Operating System
When this parameter is set to No (the default), the BIOS initializes all devices during boot up.
When set to Yes, the BIOS only performs the amount of initialization required to load the
operating system. Any other device initialization must then be performed by the operating
system.
PCI IDE Card Present in
Some PCI option boards do not comply with the PCI specification. Use this parameter to
indicate the slot number of a noncompliant PCI IDE option board. Some PCI IDE boards are
fully compliant, in which case this option is not needed. The settings are Absent, Slot 1, or
Slot 2. PCI IDE boards are never supported in slots 3 through 6. The default setting is
Absent.
PCI IDE IRQ14 Connected to
When the PCI IDE Card Present In option is used to select a slot number, this parameter is
active. The options are Edge and Level. When activated, the default is Level.
PCI IDE IRQ15 Connected to
When the PCI IDE Card Present In option is used to select a slot number, this parameter is
active. The options are Edge and Level. When activated, the default is Level.
Installed Memory Speed
Set this parameter to match the speed of the memory SIMMs installed in your system. The
options are 60 (default) and 70 ns.
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 these parameters to assign specific IRQs to specific PCI cards when ESCD data is not
being used.
