CD does not boot but BIOS correct
 
Hi,

I was given an old computer with WXP on it. It crashed on the 2nd boot . So far, so good. Either way - I wanted to re-partition the hard disks and install Debian on it.

I tried booting on my Debian CD and nothing happened - the computer tried to boot on the (crashed) hard drive. I then thought that my CD might be defective, and tried with a Debian DVD, with Knoppix and with Ubuntu. Same result.

I then cheked the BIOS, and all looked well: first boot on CD, then floppy, then HD. I then disabled the HD boot in the hope of forcing a CD boot, but it simply hung. I then wondered if the CD/DVD drive had a problem, so I downloaded HAL91 (a GNU/Linux distro on one floppy disk). It booted fine. I mounted the CD/DVD drive and I could access a CD with no problems. So the failure to boot on the CD was not caused by BIOS settings, not was it caused by a defective CD/DVD drive.

Then I noticed that when I try to boot, the computer does not even *TRY* to access the CD, it tries then floppy drive, then directly the HD. I can tell because the CD does not even rotate. All this, even though the BIOS puts the CD as the first location to boot from!!

So the problem is caused by someting else (dip switch or jumper settings?!)

Any ideas?

Thanks!

Did you burn your Debian CD yourself, and if so, did you burn it as a disk image? In other words, if you just did a drag and drop copy of the ISO onto the CD, that CD won't be bootable. It needs to be burned as an image.

I do not burn my own (Debian) CDs - I order them online. If I had burned them, I would have DDed the image rather than drag-n-drop (I am more of a CLI inclination anyway). Also - I tried *several* CDs and DVDs and none of them booted.

Since my last post here, I switched the IDE cables of the floppy and the CD/DVD drives on their slots on the motherboard and now the CD boots while the floppy does not. So the problem seems to be motherboard-based. The CD/DVD drive works fine, the I/O cable works fine, it has to be a slot or motherboard problem, no?

Any ideas?!
