Greetings, all.
After installing a new PCI board for debugging, the BIOS reported
a "Resource Conflict" error.
In addition, the BIOS did not perform even basic configuration such as
allocating base addresses and interrupt lines.
The same message was repeated for all available PCI slots.
We ignored the message and resumed system boot. It seemed that the
system started successfully.
We were able to access the configuration registers, program the device
(using PCI BIOS calls) and perform run-time accesses, but performance
was degraded and sometimes erratic.
The message and the problems disappear if we unplug this new board.
Resetting PCI configuration process in the BIOS setup screen did not
help.
We are using a PC system board that contains two IDE controllers
as well as a PCI/ISA bridge on the PCI bus.
Our BIOS is Phoenix 4.05 .
Any ideas, solutions, suggested procedures or advice are most welcome.
Thanks in Advance!
