[RULE] Install RULE on SCSI hard disk

Fri Feb 25 04:42:56 EET 2005

Thanks for the reply!

I have 2 hard drives installed in the system: the WD hard drive is
attached to the ATA card, and I have another hard drive attached to
the onboard SCSI controller.  There is no onboard ATA on the machine. 
I believe that I have to install at least something to the SCSI drive,
since I don't think the system will boot from the ATA drive
(installing RH on it gives a "non-system disk" message on startup). 
So the most important thing I can get done is to have it recognise my
SCSI hard drive.  Other distros are able to, so I must be able to load
some sort of module or something or do something in /dev.  I'm not
especially familiar with editing the /dev directory, but maybe the
solution is in there somewhere?

On board are two ide controllers, each with the expected two channels. One is the usual older type providing up to ata33. The other provides ata100 (or udma5.) My preference is to attach an ide dvd drive as a master on the primary channel of the slower ide and a udma5 hard drive as a master on the primary channel of the faster ide. This results in a GNU/Linux kernel booting up to detect the dvd as /dev/hda and the hd as /dev/hde.

My solution was simply to temporarily not use the Promise controller. Do the install, edit /etc/fstab and put the hd back on the promise controller. I assume there is no such option in your case. :((

Typing "hde" in was not accepted.

Why the kernel used after the install (with my hd switched, firstly, to the slower controller and then putting it back to the Promise controller) immediately recognises the disk on dev/hde when Slinky's does not can only point to a lack of module(s)?
