  • Get the I/O values for the card (see the Ultra DMA HOWTO above). Get these with: grep -A 10 'Promise Technology' /proc/pci | grep 'I/O' | awk '{print $3}'.
  • \r\n
  • Add these values to your bootloader. Examples (your I/Os will vary). In LILO, eg: append="ide2=0xb400,0xb002 ide3=0xa800,0xa402", in GRUB, on the kernel line: ide2=0xb400,0xb002 ide3=0xa800,0xa402. SEE THE HOWTO FOR THE PROPER VALUES. REPEAT: SEE THE HOWTO FOR THE PROPER VALUES.
  • \r\n
  • Add the kernel module to /etc/modules: echo pdc202xx_new >> /etc/modules
  • \r\n
  • Reboot.

Much happiness. I've got /home and 74 GiB of free storage ;-)
