Talking Getting Linux to work on Promise ATA100

Hi. I have ASUS A7v Motherboard and dual boot (or am attempting) Win98/Linux on 2 seperate partitions on 30gig HDD. Using the ATA66 IDE on my motherboard (ASUSA7V has ATA66, and ATA100 IDE's) I can install and run Linux Redhat 7.1 or 7.2 just fine. However, I want to be able to use the ATA100 on my motherboard while in Linux. If I attach my HardDrive to the ATA100 IDE on the MOBO Linux will not boot. I understand that Linux is not "seeing" the ATA100 IDE and i have to feed it the address's or something but I dont know how to do this. Any help would be appreciated

Lover of Linux and its command line oppurtunities

OK, so what are you doing?
Are you installing Linux when the harddisk is on one IDE channel, then swapping the harddisk over to the second IDE channel?

Linux recognises the partitions by what channel they're on, regardless of if there are any other devices present. Here is the rundown:

1' Master = hda
1' Slave = hdb
2' Master = hdc
2' Slave = hdd

If you install Linux when the harddisk is on hda, then swapping the harddisk over to hdc is going to cause problems. You could try this:

Have the harddisk on the ATA100 controller. Reinstall RH.

You probably could boot from the CD, enter rescue mode, edit your lilo.conf (or the grub one), and edit your fstab, so that everything points to the correct devices, but it is potentially much harder than just booting from the CD and installing the OS when the harddisk is on the 100 controller.

Keep us posted.

here's what im doing or had done

thanks for responding. When I attempted an ATA100 IDE install of Redhat 7.1 I was on the ATA100 master channel. First It would not install because it could not see that channel for some reason. I had read on the web of someone saying to pass the addresses of the ATA100 IDE to Linux on install which I tried to do. I got some sort of error though when I had began the actual install. Someone else had recommended that I install Linux on the ATA66 and then edit some file to point to the address of the ATA100 IDE.
Im really confused about all this anyways and didnt install Linux since. But now I want to reinstall Linux and learn on the side about it and some C programming so I am going to reinstall it on
a partitioned 30 gig HDD.1st partition will contain WIN98 and second will contain Redhat 7.2. If there is no easy way to install to ATA100 I will just install to ATA66. My main reason for wanting to install to ATA100 was to take advantage of the speed for Vid capture that I do occasionally. If you or anyone knows of a way to install to ATA100 IDE that would be great because I keep running into errors and at this point it being a while I cant remember those errors of hand to write here.
