[COLUG] AOpen DVD drive issue

[Dave]

I got a new custom computer (from TCR in Pickerington) for my wife's  
office and am having issues with the DVD drive. I burned a DVD of  
CentOS 5 and it loads ok and brings up the first screen, but once I  
select to install from the "CD-ROM" drive, it says it needs a driver.  
So I created an image of the DVD on my Mac and did an ftp install  
which worked fine.

After the installation, I still can't get the DVD drive to recognize  
any disks. I put a music CD in and it didn't recognize that either.  
I'll need to call TCR tomorrow to get the exact specs, but the  
invoice says it's an 18X DVD +/-R/RW IDE burner and the label on it  
says it's an AOpen. I can't even identify the drive at aopen.com for  
certain. And a google search for aopen dvd burner driver didn't turn  
up anything useful. I've never had an issue with CD or DVD drives  
with Linux before (although this is the first time in a couple years  
that I've installed Linux - and the first with a DVD burner) so I'm  
stumped.

The hard drive shows is /dev/sda - there's no other /dev/sd and no / 
dev/cdrom, or /dev/dvd anything after the install.

Any ideas? It's not crucial that I get it working, but I would like  
them to be able to burn backups to it.

Thanks,
Dave
