RH7.1 IDE-problem

[Freddy]

I have a PC with a Pentium 100Mhz processor, a intel chipset, a 1Gb ide drive and a 4Gb SCSI drive.
I had RH7.0 installed on it and used the ide drive for LILO, the /boot and the swap partition.

Now i have installed RH7.1. The problem is that RH7.1 doesn't recognize the ide controller (not the harddisk or the cdrom attached to it). The SCSI card doesn't support booting from it so i have to boot from a floppy.

There is a little DOS6.22 partition on the idedrive that i can boot from so the hardrive is stil working only Linux RH7.1 doesn't recognize it. I've read several Howto's but can't find any solution for solving my problem. Has anyone had this problem before, or has anyone any idea where i have to look for a solution.

When I type dmesg in linux to look if the ide controller is present i see the following sentences:
-Uniform Multi-Platform E-IDE driver Revision: 6.31
-ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
-RZ1000: IDE controller on PCI bus 00 dev 08
-PCI: Enabling device 00:01.0 (0000 -> 0001)
-RZ1000: chipset revision 1
-RZ1000: not 100% native mode: will probe irqs later
-ide0: disabled chipset read-ahead (buggy RZ1000/RZ1001)
-ide1: disabled chipset read-ahead (buggy RZ1000/RZ1001)

How did you get RH7.1 installed if it doesn't recognize the ide controller? Anything special you had to do and if so, could it be added to the boot process?

Any other error messages you could post?

I did install RH7.1 from cd (there's also an scsi cdromdrive in the machine) I started with the install bootdisk from the cd and made a driverdisk (also from the cd). I didn't get any messages about the ide-controller during install but during install I had to make patiotions on the drive with fdisk. The only drive that was showing was the scsi-drive so I installed RH oon that drive

Anything in the bios you can change to allow booting from the ide drive? Disable the SCSI bios so it doesn't boot from the scsi drive?

Sorry I can't thing of anything else.

Have you searched around Redhat's support site or usergroups? Google search?

There are no special settings in the bios i can change. I removed the scsi-card and tried to install RH7.1 but then it is looking for a cd which it cannot find. I think it must be something in the kernel because RH7.0 has no problem with de ide-controller.
Anyway thanks for replying (think i have to learn how the kernel works and what part is responsible for ide.)
