Portion of /tmp/syslog from installer
I would have included the entire syslog, but as the install completed, I got a spew of EEPRO100_WAIT_FOR_CMD timeouts and the machine locked up. I was doing an NFS install. Assuming that the new DID:248b is the same as DID:248a, I have created the attached patch. This causes the PCI device to be identitfied as a PIIX4, but still no joy due to a "resource collision". Not sure how to track down the resource collision. DMIDECODE reports "checksum error" and fails to print much of any use to me. # dmidecode PNP BIOS present. RSD PTR found at 0xF5D00 checksum failed. OEM ACPIAM Any ideas on how to track down the resource collision? Created attachment 50765 [details]
Patch to make piix.c service 8086:248b

dmesg from patched kernel
Resource collisions are bios bugs.... We need to get confirmation from one of the ide people that this chip in deed is a piix4; this might or might not make the release..... at least it works even without the ident. please test 2.4.18-0.19 or 2.4.18-0.20 in rawhide It should have this working (some of these messages are still bios bugs it seems, but unavoidable if the hw needs to pass MSFT certification) I find 2.4.18-0.21 in Rawhide today. Will download it then install skipjack/beta4 and that kernel and see what happens. Is there a new dmidecode as well? What are the MSFT compatibility issues? No new dmidecode; that looks like a bios bug Microsoft seems to require the PCI BAR's to be in a certain state (off mostly :) and ACPI is the only thing that can enable them then. any news on the kernel ? Sorry for the delay... The 0.21 kernel did not solve the problem. However, the following sledgehammer of a patch did... Basically, I told the pci-i386.c functions to ignore the fact that a region on a PCI device had not been allocated an address. Reading the Intel specs for the 82801CA chip suggest that it has a "legacy" and "native" mode now where the first 4 regions (0 to 3) can be used to decode the command and control registers for the primary and secondary interfaces independantly. Perhaps this makes a device driver easier to write? In any case, this would seem to clearly suggest that Tyan's got a BIOS bug. They either need to allocate the regions, or disable them. Either way, the Linux device driver doesn't (currently) use them and won't care. Created attachment 53904 [details]
Disable PCI EINVAL on unallocated regions
