Heading Option Description
Advanced*
(continued) ISA PnP Devices
•
Lists current settings of Plug and Play (PnP)
devices
•
Enables or disables PnP devices.
•
Allows you to change the configuration of PnP
devices.
Note: Option will not appear if there are no PnP
devices currently installed.
Bus Options Allows you to set:
•
PCI bus mastering, which allows a PCI device to
take control of the PCI bus (enable/disable)
•
PCI reset on warm boot, which asserts the PCI
signal RST# during a warm reboot
(enable/disable)
•
PCI VGA palette snooping, which sets the VGA
palette snooping bit in PCI configuration space;
this is only needed with more than one graphics
controller installed (enable/disable)
•
ISA back-to-back I/O delay: Fast allows I/O
transactions on the ISA bus to immediately
follow each other (fast/legacy)
•
Bus priority: PCI gives more access to the PCI
bus; ISA gives more access to the ISA bus
(ISA/PCI)
•
I5-MB memory hole: enable won’t allow the
memory decoder to decode addresses between
15MB and 16MB; disable allows the memory
decoder to use the 15MB to 16MB range for
normal memory use (enable/disable)
* These options should be used by advanced users only.
