ODD0: LITE-ON DVDRW LH-20A1H ODD1: CD-RW CDR-9V52 appears briefly on the screen. I have never used RAID - perhaps I'll get to it - so I ignored this message. In retrospect it seems so obvious and I feel pretty stupid. I went to /usr/src/linux-source-2.6.18 and found JMicron JMB36x support in /Device Drivers/ ATA/ATAPI/MFM/RTL Support. With this as a module I how have hde and hdf in /dev plus a slew of cdrom2, cdrom3 cdrw2, cdrw3, dvd2 and dvdrw2 soft links. There remains an underlying problem with the ECS KA3 MVP motherboard BIOS. It will only start booting a system CD if one of the two optical drives is in the boot sequence by name. The boot sequence floppy/cdrom/hard drive will always default to hard drive as there is no cdrom. On the other hand only the grml CD will boot from one of my optical drives. All the other system CD's I have - Sarge CD #1, Knoppix 3.3, Knoppix 5.0, bbc-2.1, a rescue CD made with mkrescue - all fail. Each of them starts to load and then stalls - perhaps because they are looking for the non-existent cdrom drive. I can live with this as with the 2.6.28 kernel and the JMicron module Etch loads and runs perfectly from the hard drive. I had hopes for Knoppix 5.0 which I downloaded this morning and for the rescue cd which was also made today but, in an emergency, there is always grml to fall back on.
