I added a 120GB hard drive in my 166, and I encountered the 8GB limit, so I just used a IDE Raid Controller card I had sitting around. I could mount the hard drive at the boot disk prompt by typing:

mount root=/dev/hda1 ide2=0xfff0,0xffe6,10

It could then access the drive, but when I did a df it had a limit of like 4 GB (WTF?!) Suffice to say, I turned off the onboard controller primary. I hooked up the root drive to the controller card in hopes that I could use both on it. I booted up and it gave me a VFS root error. I did a ls /proc/ide
but it came up with just the cd drives. The /proc/pci came up with a irq 10, but I tried using the ide2= method to load it and neither would mount that way.

My question is: How can I get linux to recognize both drives on boot using the ide raid controller card?
Thanks in advance to anyone who can help me!
