RE: IDE Card

["Mugleston, Brad" <brad mugleston gwl com>]

Mark, Richard and everyone else,

Thanks for the replies - we've established that the SCSI card I see under
windows that I have my CD's connected to is the same device I see under
Linux in the /proc/pci file.

Now how do I mount my CD's?   I made a directory called (cdu - for CD upper)
and did a mount /dev/hd* /cdu and got an error (it was late last night and I
didn't write it down, sorry -something like that device isn't there).  I
tried all kinds of combinations to replace the * (c, c1, c2, d, d1, d2, b,
b1, b2...) but I got the same error (no I didn't really use a *, just the
replacements).

Thanks for any help anyone can give me - I'd like to get this working over
the weekend so if you believe you have a solution can you also send your
reply to my home email address of  muglesto ecentral com

Thanks

Brad
