The kernel/driver (2.0.34 at the time) didn't recognize the LBA translation, so I had to specify hdd=1653,255,63 as kernel boot parameters. I thought I read somewhere (kernel source, HOWTO, or somewhere) that the probing or BIOD lookup or something didn't work on the secondary controller, but I looked just now but couldn't find it again. When I moved the disk to hda, it came up with 1653/255/63 without needing the boot parameter. Sorry I couldn't find the details for you, but at the time I convinced myself that I was seeing normal behavior. I actually don't even know if it matters one way or another. I figured it did, because I wanted to make a 1023 cylinder partition that was as big as possible, so I needed the LBA translated values. ...RickM...
