cdrom at ata1, eject cdrom at ata2. I then rebooted and the CF worked
w/o incident (I didn't try before the reboot). Sorry I wasn't clear.

Yes. Here's more details, lemme know if you need more. Looks like
the floppy driver needs a little work. Or it might just be the two
windows problem. What's in the altstatus register? What is it used
for?

Yes. That was a comment about the pccard attachment code not being
completely right. Sorry I wasn't clear. I know how to tell the
difference and hope to make a small change shortly.
