CDROM DVDROM issues

By Oz_Media ·
Okay this one is getting to me now.

Customer brings in IBM PC with CDROM and DD burner not working. They show up in System Hardware properties but with error code C10 failed to initialize. PC DOctor tests reads fie on both. BIOS seems to be okay with them too.
Unable to boot from them to reinstall Win2K.

PC: IBM Netvista 6578-NDU

I have:
-Flashed BIOS after resettng CMOS and BIOS via MOBO jumpers.
-Swapped ribbons.
-Tried with only one drive or the other.
-Tried using JUST one drive as a slave on primary ribbon with HD (incase mobo connector was dead.
-Tried an older CDROM
-run full PC Cotor diagnostics, passed all tests.

WHAT AM I MISSING!?!?!?

Any help is greatly appreciated !

Post here or email me ozmedia@excite.com, points still awarded if resolved through email.

THANKS!
OM

OM,

To boot from Win2K CD try the following (assumes that BIOS will properly recognize drive).

Connect only CD-RW drive as jumpered master (not cable select) on secondary IDE adapter.

I know you have tried similar tactics, but this particular configuration is most reliable available.

Let me know what happens.

Also set boot sequence to Floppy then CD-ROM then HDD-0.

Thanks very much for your response but yes that's already been tried.

I figured a basic config as you have suggested would be easiest, but no go.

Any other ideas?

Willcomp.

The CD light comes on for a second, it starts to spin up but doesn't seem to get all the way there and isn't readable. (Did try different disks)

It checks the floppy, then the light on CD is on for maybe two or three seconds, spins CD and stops, then boots from HD.

Windows just boots but th edrive is coming up as unable to initialize C10. I tried different power supply just in case.

That is really sounding like a flakey UDMA controller.

I'd call IBM and see what they are saying on it.

One thing that you can try is to set the bus under Windows to use PIO only, some drives get in trouble with DMA. If the bus resets, make sure that the burner software is updated.

Since you can't boot from drive, we can rule out any Windows settings as the culprit. Appears that we are strictly dealing with Mobo, BIOS, cables and drive at this point.

Only other thing I know to try is select no drive or Cd ROM drive in BIOS versus Auto for optical drive and see if that helps. It does on some older systems.

Have also seen problems booting from old, slow CD ROM drives (can't load fast enough) where several tries were required to boot. Don't think that's your problem here.

Other than a mobo glitch, I am out of suggestions. You've pretty much tried everything else.
