Hi everybody,
I was finally successful in getting my Promise FastTrak TX2000
(PDC20271) to work with Linux 2.4.19 on Redhat 7.3 and I thought
I'd pass along the secret :)
I used the config file from the Redhat 2.4.18-3 source directory
(/usr/src/linux-2.4.18-3/configs/kernel-2.4.18-i686.config) and did
not make any modifications to it.
These were the default settings:
CONFIG_BLK_DEV_PDC202XX=y
CONFIG_BLK_DEV_HPT366=y
# CONFIG_PDC202XX_BURST is not set
# CONFIG_PDC202XX_FORCE is not set
CONFIG_BLK_DEV_ATARAID=m
CONFIG_BLK_DEV_ATARAID_PDC=m
CONFIG_BLK_DEV_ATARAID_HPT=m
after running "make oldconfig" and doing the kernel compile
groove, I created a ramdisk:
mkinitrd --preload ataraid --preload pdcraid \
/boot/initrd-2.4.19.img 2.4.19
Then based upon the controller information obtained from /proc/pci
and the instructions here http://www.murty.net/ataraid/existing.html
I created an "append" line:
Bus 0, device 11, function 0:
RAID bus controller: PCI device 105a:6269 (Promise Technology, Inc.)
IRQ 5.
Master Capable. Latency=64. Min Gnt=4.Max Lat=18.
I/O at 0xdc00 [0xdc07].
I/O at 0xd800 [0xd803].
I/O at 0xd400 [0xd407].
I/O at 0xd000 [0xd003].
I/O at 0xcc00 [0xcc0f].
Non-prefetchable 32 bit memory at 0xcfff0000 [0xcfffffff].
I then modified /etc/grub.conf:
title Linux (2.4.19)
root (hd0,0) kernel /vmlinuz-2.4.19 ro
root=/dev/ataraid/d0p2 ide2=0xdc00,0xd802,5 ide3=0xd400,0xd002,5
initrd /initrd-2.4.19.img
And modified my /etc/fstab:
/dev/ataraid/d0p1 /boot ext3 defaults 1 2
/dev/ataraid/d0p2 / ext3 defaults 1 1
/dev/ataraid/d0p3 swap swap defaults 0 0
After putting the new kernel and ramdisk in the appropriate
places and rebooting, the controller worked:
df -k
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/ataraid/d0p2 37832032 3852384 32057876 11% /
/dev/ataraid/d0p1 101089 18810 77060 20% /boot
Have fun!
Barton
