The special cas with my setup is, that I have an ICH4 onboard, an PDC20276 onboard and an PCI SCSI controller. The root filesystem is on the SCSI disks. I can not boot from the SCSI disks directly, as the BIOS enables the PDC first. So I have to boot from the IDE disks connected to the PDC. This didn't work, so I replaced the simple Promise RAID bios with an normal UDMA bios thats allows you to use the controller as normal IDE controller. The result is, I can boot from the IDE disks and I can use the IDE disks as normal disks (used it in times the CONFIG_PDC202XX_FORCE wasn't in the linux kernel). I do not know if the PDC 20276 is being sold with such a normal bios. I think so, as there are serveral users reporting the same error. The problem is, that the driver thinks the bios/drives didn't get enabled by the bios end disables the whole controller. I patched the driver to skip this step. I still have to use the CONFIG_PDC202XX_FORCE setting- without it the second channel gets disabled. This is the reason for my patch. I'm not sure, but I this it shouldn't be a problem for the driver... Regards, Arne PS: please write me if you see any problems related to that patch Bartlomiej Zolnierkiewicz wrote: BZ> It MUST work.
