Not really, but I didn't like the driver which came with one of my CDROM 
drives so I replaced it with one I got with another no-name OEM CDROM 
drive. I'm not sure who wrote it, but there's an Acer copyright message 
in it. For what it's worth, this driver is in use with three different 
OEM drives. I've had several ATAPI CDROM drivers, inc Mitsumi, and they 
all work to some extent on any of the drives I have so you could 
probably trawl the CDROM makers sites and try other drivers.

IDE or ATAPI ?
I've found ATAPI easier to get going than IDE, but in the UK, at least, 
they tend to get sold under the same "IDE" label. I have the feeling 
that ATAPI replaced IDE, but I don't know.

CDROMs, in my opinion, should always be the last thing looked at since 
it's my belief that they don't fully implement the ATAPI interface spec.
I'd have installed it as the slave under the ZIP on the second IDE port.

It should be OK in command line mode, but the GUI mode is a known 
problem which 7.03 BETA fixes, among other things. If you're a DRDOS 
user, I'd strongly advise using 7.02 with the 7.03 updates.
