There is some limited support for this in current via tha atacontrol command. I'm not sure what the MFC status is. I've had reasionable success with booting with the CD/DVD drive installed and then pulling it and inserting a floppy (since they detect even if they aren't there.) As long as you don't access the non-existant ATA drive it seems to be OK, but I rather doubt this is recommended and a little forgetfulness leads to crashes this way. > *) can I get the DVD drive to run in DMA mode?

If the machine doesn't crash when you access the device you're good. ;-) > *) I guess noone has tried to write an IrDA stack yet, so I can't use the > Infrared port? There's an ongoing effort to write an IrDA stack in netgraph, but progress has been slow, at least in public. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
