Can't install from Optiarc DVD RW AD-7170A

[Ashley Moran]

Hi

Just bought a new cheap PC as a server.  It's got an Optiarc DVD RW  
AD-7170A drive (according to the BIOS), but you can't install off it.

If you boot off an install CD (including the 7.0-CURRENT for August)  
and try to start the live filesystem, the debug console shows this  
output:
   acd0: FAILURE – READ_BIG HARDWARE ERROR asc=0×08 ascq=0×03
   g_vfs_done():acd0[READ]error = 5

I don't know what to do with this information or how best to report  
it, so I thought I'd post it here.

Here are the full drive details from the BIOS:
   Device: ATAPI CD-ROM
   Vendor: Optiarc DVD RW AD-7170A
   LBA Mode: Supported
   PIO Mode: 4
   Async DMA: MultiWord DMA-2
   Ultra DMA: Ultra DMA-2
