The CD burned from the iso wouldn't even try to boot; the machines - both of them- didn't recognize it as a bootable CD; they timed out and booted from the hard drive. I even tried in a more modern (but still old) machine, a 1.7GHz Celeron; same result. md5sum checked OK on the iso.

Yes, strange things happen.

Please read isolinux/README.TXT on the CD or from the mounted image.

OK, I read that file (or tried to). Gotta tell ya, it's WAY over my head. I doubt I'd be able to successfully build the installation CD's discussed there, and I couldn't find where it's stated explicitly that the downloaded iso wasn't bootable. But that's just my (in)experience level exhibiting itself, I guess.

I'm terribly sorry to have shown you this text, especially since it probably really does not help you. I try again and probably we come to a viable proposition.

You could not boot the CD with slackware-current-mini-install on three computers. Neither on both HOH, nor on the old, but newer Celeron.

It is very unlikely that the optical drives of all three computers to be defective at the same time. Therefore I excluded defective drives. But you have installed Ubuntu on the AMD K6-2 computer. If you can use the drive to read, it's not broken. Also you could try again to boot the Ubuntu CD and thus check of the drive is still working.

For the inabilities to boot, two other reasons may come into question, to my knowledge.

The first reason may lie in burning the CD. If the CD was written at too high speed, then it is usually not readable, i.e. not mountable or bootable. If the CD can not be mounted or read, but other CD's work on this drive, then the CD is bad. Burn then slackware-current-mini-install.iso again, but not faster than 2x or 4x.

The second reason for the boot deny may be in the BIOS. There are several modes through which the BIOS can boot from CD: "floppy emulation mode", "hard disk emulation mode" and "no emulation mode". In the first mode, the boot information is stored in a FAT floppy image file on the CD. This will be loaded and then used as a virtual floppy. In the second mode, the boot data is part of the CD-structure and be used directly from there. In the latter method, the BIOS must know itself, what to do in order to boot from CD. (all according to my memory, so it can also be somewhat inaccurate)

The slackware-current-mini-install.iso image has been created by mkisofs command using the switch "-no-emul-boot". Thus an image can be booted on a fairly modern computer. If your HOH BIOS is very old and therefore can not do without emulation, it sees nothing bootable on the CD.

First you may check if the CD was burned bad and therefore is unbootable. Because you can not boot the CD on a fairly modern Celeron computer, I think mainly on a poorly written CD.

At last but not least, the slackware-current-mini-install.iso image can be booted. I have no computer with AMD K6 CPU. I can boot the image on a computer with AMD Sempron, but that is AMD K8. And I can boot it on Intel Celeron (Pentium III). This is the oldest hardware I own.

It's all just a matter of proving that the error gapan has pointed to, is already fixed for AMD K6 in Slackware current. Then you could use Salix 14.2 on your HOH later.
