No matter what flavor Linux I use my new Sony DVD/CDROM RW drive won't
boot from or recognize DVD media. One warning message from Debian said
that because I didn't have an 80 wire cable I was restricted to a
speed of 33 units. I also wonder if my AMD cpu etc. purchased some
years back is limiting me. I can set various boot devices in the bios
but DVD isn't one. CDROM is and works fine from the same drive.

I don't have the exact specs on my cpu and motherboard but this is
what
dmesg shows:
/CPU0: AMD Athlon(tm) Processor stepping 02
SMP motherboard not detected.
Local APIC not detected. Using dummy APIC emulation.
Brought up 1 CPUs
NET: Registered protocol family 16
ACPI: bus type pci registered
PCI: PCI BIOS revision 2.10 entry at 0xfb620, last bus=1
PCI: Using configuration type 1
Setting up standard PCI resources
ACPI: Interpreter enabled
ACPI: Using PIC for interrupt routing
ACPI: PCI Root Bridge [PCI0] (0000:00)
PCI: Probing PCI hardware (bus 00)
Boot video device is 0000:01:05.0
....
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx

I think the cpu is an AMD K7 780Mhz

1. Is the 40 wire cable a killer?
2. Do I need an upgraded cpu?

May be teaching you to suck eggs here...

Have you enabled booting from DVD in BIOS? You need to set the DVD to be
earlier in the boot order than the hard drive(s).

There were some older DVD-ROM units that had a hard time reading DVD+R
media. If this is a new drive, it should have no problem reading DVD-R,
DVD+R, and the RW variants. Does it handle DVD-ROM? Does it recognize
CD-Rs? If it will mount CD-R and won't mount DVD-R, it has a mechanical
problem or a firmware problem. New drives should have neither of those
things.

Yes, you have to do this. However, if it can boot from CD and not boot
from DVD, BIOS boot order is not the problem.

Good point, missed that line.

Another question, will other/older distros boot from DVD? There is a bios
issue with some systems. I personally know little of this but it has been
discussed in alt.os.linux.slackware
