IDE DVD-ROM drive dosen't show up in BIOS, but works in Windows...weird

[JackHawksmoor]

Just wondering if anyone's had this happen before, and if I should be concerned. On my old motherboard my Pioneer DVD-ROM drive showed up in the Bios like normal, but it dosen't show up at all on my new one, no matter what channel I put it on. My slave HP CDRW DOES show up in the BIOS.

DOS and Windows DO see the drive though, and it seems to work like normal. I just didn't think it was possible for something to not be seen in the BIOS and then work in Windows.

Do you have the ide detect set?

choose autodetect for the drive in bios & then it should be correctly detected.

 

[JackHawksmoor]

You mean like set to auto detect in the BIOS? I've got all the drives set for that, and my DVD is set for master and my CDRW is set for slave (versus cable select). This just seems weird.

bios

mine is weird too.
HP CDRW will show up at the first time. If I restart windows, it won't show on the boot up screen. My other CD-Rom will show up, but not this CD-RW.
And if I press reset, it will show up again ....
However, either way my windows will detect the CD-RW no problem ....

Well... I'm not sure if this is what you guys are talking about, but both my cdr and dvd rom drives, they show up on the bootup screen, but are undetected in the bios, both work fine under Win2K.

Hmmm, I had that too.

I had to do something else AS well as autodetect, but I cannot remember what

 

[JackHawksmoor]

Huh. I had never heard of this before now. Didn't even know it was possible (I thought everything went through the BIOS in some form or another). But I guess we don't need to worry.

Well, if anyone figures out how to fix it, or what it means, let me know!

swap the drives... make the DVD slave and the CDRW master...

I had the same problem... the only way i could get the drive to show was setting the jumpers to slave or csel.

what DVD drive is this anyways?

It doesn't matter if the drive is viewable in BIOS, as long as WIndows can use it. I remember back when it was preferred to disable the drives through BIOS so that they woudln't mess up bootup or anything (before booting from CD was that stable). If you don't want to boot from CD it doesn't matter.

Some ATAPI devices don't dtect well in the BIOS, its not a problem as long as the windows driver finds them. Your only problem will be if you want to boot from CD, they must be able to auto-detect before they will boot.

Thanks for the suggestion. I think I've already tried that combination though. At one point the DVD showed up briefly, but a few reboots later and it dosen't show. It's a Pioneer drive, BTW, 16x tray loading.

Oh well, if other people run it like this, I'm not so worried
