Appendix B PCI to CardBus Bridge Utilities
Introduction
The PCI-to-CardBus Bridge DOS Utilities are provided to be used on DOS PCI sys-
tems that do not have PCI-to-CardBus bridge (herein referred to as PCB) BIOS support.
They are to be used to fill-in the gap there are to be used temporality until your system
has another software for CardBus support (i.e. Card and Socket services).
Utilities Description
These utilities are provided for the developer who intends to write drivers or diagnos-
tics for a device that is downstream of (behind) a PCI-to-CardBus bridge. These utilities
are intended only as a short term solution, until the target system is upgraded with a BIOS
that supports PCI-to-CardBus bridges.
There are three utilities available in this release:
1. ADJIRQ.EXE
Usually the PCI BIOS assigns resources at boot time. Most of the BIOS do not sup-
port the CardBus bridge, and hence in most of the cases will not route PCI inter-
rupts to the CardBus bridge.
In case that the BIOS supports fixed interrupts routing per PCI slot, there is no need
to use this utility.
In all other cases, the user might need to use this utility. If the BIOS did not assign
interrupt to the CardBus bridge, the CardBus card will not generate an interrupt, and
so it's functionality will be partial.
Note that not all interrupt numbers are available for PCI. Usually the following IRQs
can be used for PCI: 5, 9, 10, 11, 15. It is system specific.
In case that the interrupt you select is not routable, the utility will print a notice.
Utility can route IRQs only on systems with PCI BIOS rev 2.1!
