SuSE 8.1 and SCSI emulation
Here's as weird one: I have just installed 8.1 on my trusty Athlon that works fine with 8.0. I have a Toshiba DVD on hdb and a LiteOn CDRW on hdc. 8.0 correctly configured lilo and initrd to load SCSI emulation for HDC and all was well. With 8.1 SCSI emulation sees both the DVD and CDRW as SCSI devices, although grub is configured with hdc=ide-scsi. To make matters worse it thinks that both devices have 7 logical devices so I end up with 14 SCSI devices!! I can probably live with having 7 CDRWs but I would rather like to the DVD back to being recognised as an IDE device and not a SCSI device. Does anybody have any ideas, should I revert to using lilo instead of grub, or is it a problem with the ide-scsi module. TIA David Bottrill

I have done a bit of checking on this, as this happened to me with every 'unofficial' kernel update I installed. After checking, this is the scoop. If the ide-cd module is compiled into the kernel (not a module), it will recognize the line hdc=ide-scsi, ignore that drive, configure the other drive for IDE, and when the ide-scsi module loads, it works for only that device. If it is compiled as a module (not in the kernel), it does NOT recognize that line, and the ide-scsi module loads and finds 2 compatible drives. I haven't found a way to get the ide-cd module to control the DVD unless I don't load the ide-scsi module, which means I can't use the writer, so I am currently using the ide-scsi module for both. If any more wise souls know a way to get each module to control each drive, I would also like to know. :-) -- Joe & Sesil Morris New Tribes Mission Email Address: Joe_Morris@ntm.org Web Address: http://www.mydestiny.net/~joe_morris Registered Linux user 231871 God said, I AM that I AM.

Same with me here. Both my dvd and cd-rw were configured as scsi devices, about 12 of them....I have not figured any way out of this yet , but cannot possibly see how such an occurence failed to be spotted by SuSe. Regards, Josef David Bottrill wrote:

I've got the exactly the same problem although i've physically only got 2 cd drives Suse diplays 8 of each! Mind everything seems to work ok ie cd writing etc, but it is rather irritating Richard G. On Sunday 06 October 2002 09:30, Josef wrote:

Use max_scsi_luns=1 on the append line in LILO or the kernel line in GRUB for each boot configuration you need. This limits the number of scsi devices seen for the ide-scsi device emulated. Next issue is how to get them removed from the KDE Control Center/Information/Available Hardware once you've installed with all those extra devices enumerated. Stan Richard Gelling wrote:

Thats great , thanks, It's cerainly made the start up cleaner without reporting all the phantom drives. Just need to sort out the control centre part now. Thanks alot Richard G. On Tuesday 08 October 2002 17:02, SRGlasoe wrote:
