It seems that wd1 intercepts > whatever incantation I use (sd1, hd1, etc.) The bios boot code recognizes hd0..hdN based on the order of the BIOS probes. That should make your sd1 show up as hd3. Question: I have wd0, sd0, sd1, and I boot from sd0 (from before I had the wd0 drive). When I was running 2.0.5, I patched the boot code to default to hd1 so that after getting the secondary boot block off of wd0, it would actually boot from sd0. After I installed 2.1.0, I made the same change. Now, however, after successfully booting from sd0, the kernel panics because it isn't pointing at sd0a as the root device. What did I miss? --Ben
