*This message was transferred with a trial version of CommuniGate(tm) Pro* Hi RAIDers, I'm in the middle of a system upgrade on a machine whose motherboard failed. While I was at it, I figured I'd upgrade to RAID. However, I haven't been successful. Before I go out and DOWNgrade my motherboard, I thought I'd ask if anyone's actually got a Promise PDC20376 to run with Red Hat 9.0 or any 2.4.20 kernel. Here's what I've done. I read this list and then went out and bought: Red Hat 9.0 ASUS A7V8X Mother Board (with Promise PDC20376, yes, 20376, not 20276! ) 2x Seagate 80GB Barracude SATA HD I currently have the machine running (kernel 2.4.20-19.3) on its old IDE drives for /, /usr, /boot but can't get it to recognize the RAID. I've used the Promise BIOS to configure the two disks in Raid0 (Striped) and that seems to be fine at the BIOS level. /proc/pci sees the devices: Bus 0, device 8, function 0: RAID bus controller: PCI device 105a:3376 (Promise Technology, Inc.) (rev 2). IRQ 10. Master Capable. Latency=96. Min Gnt=4.Max Lat=18. I/O at 0xd400 [0xd43f]. I/O at 0xd000 [0xd00f]. I/O at 0xb800 [0xb87f]. Non-prefetchable 32 bit memory at 0xf3000000 [0xf3000fff]. Non-prefetchable 32 bit memory at 0xf2800000 [0xf281ffff]. Correspondingly, I've passed ide2=0xd400,0xd000,10 on the "append line" All the *PDC202XX kernel CONFIG parameters are turned on in my kernel (they were on by default in the installed kernel). And, yet, I still get: -bash-2.05b# insmod ataraid Using /lib/modules/2.4.20-13.9/kernel/drivers/ide/raid/ataraid.o -bash-2.05b# insmod pdcraid Using /lib/modules/2.4.20-13.9/kernel/drivers/ide/raid/pdcraid.o /lib/modules/2.4.20-13.9/kernel/drivers/ide/raid/pdcraid.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg -bash-2.05b# I'm assuming that the 2.4.post18 kernels only supported the 202XX chips while this motherboard has the 203XX chip. Its my fault for misreading the chip number when I spec'd the motherboard but if you can help, I'd sure appreciate it. Thanks, Reid. -- Reid Spencer <reid@xxxxxxxxxxxxxxx>
