Added CD; won't boot

[Wanna Learn Linux]

I've gotten into Knoppix and like it so much I wanted to add a second CD
drive to my Gateway E-4400. So I did.
And now Knoppix won't boot from the CD drive anymore.
Both drives show up fine in Windows but when I try to boot
Knoppix it just goes ahead and boots from the hard drive. I can
disconnect either CD drive and Knoppix boots fine from the remaining one.
Any suggestions?

Sounds like a BIOS problem, your motherboard may not know which drive to boot from if they are both connected. Are they both on the same IDE channel? Check out if you can set the boot order in the BIOS when both are connected.

Also make sure one drives jumpers are set as slave, and one as master. If theyre both set as master, it will give you problems booting from them.

It's now booting. Not real sure how. Knew it had to be a combination of BIOS settings and jumpers. Worked on it most of the afternoon and finally got it. Crazy thing is, it's only booting on one CD drive which is older than some of the others I tried.

Guess this wasn't really a Linux-specific question. Sorry. Thanks for the comments.
