Ahh here's the rub, I started with a clean HD, installed DOS and then W98. During the DOS install I used Adaptec's find the SCSI devices and add them to autoexec and config thing, thus negating a need to install anything from Plextor. W98 picked up on the fact that I had a SCSI CD and CDR and accepted them.
I later had to inform W98 that I have SCSI CD and CDR's but it never asked for a driver install for the CD. As far as 98 goes it's happy just knowing I have a SCSI CD installed. It doesn't give a [-peep-] as to what brand. I'm assuming that if I install some sort of Plextor driver it will give me the version for the firmware in the CD, but I was hoping there was some tiny file I could get that would search the version for me.
Nowhere, and I mean nowhere, can I find the version in any reportable agent that looks into installed hardware via 98.
So I thank the posts telling me I can find it in device manager, BIOS etc. but nope theuy don't show the deal. I had thought of that from the beginning.
