All, In reply to "pdcraid won't work when using CONFIG_PDC202XX_FORCE (Martin Stjernholm)". I had the same problems with this a well - only I am using RAID 0 - it took me a while to figure this out. I posted an item titled "Problems with 2.4.19 Kernel and Promise Fastrak100 RAID Controller (2.4.18 works) (Alan Miles)" on 05-Aug-2002 regarding this. >> When I tried to get the Promise PDC20276 working in RAID1 mode on my >> Asus A7V333 running Linux 2.4.19, I encountered a problem due to >> seemingly confusing docs: >> According to the instructions on http://people.redhat.com/arjanv/pdcraid/ataraidhowto.html, >> and on "Promise Fasttrack RAID Howto" (http://www.magic-lamp.org/howto/pdc20265-mandrake8.2.phtml), >> I set the kernel option CONFIG_PDC202XX_FORCE (aka "Special FastTrak Feature"). >> The kernel wouldn't detect the disks on the RAID >> controller. When I disabled that option (no other changes at all), it worked. When I set "CONFIG_PDC202XX_FORCE=y" to: "# CONFIG_PDC202XX_FORCE is not set" in the config file and then recompiled the 2.4.19 kernel, it solved my problems. Obviously there is something wrong with this code. Alan
