>Description:
When using a Colorado Jumbo 250 tape drive (QIC 80) on a 486 with a 
multi I/O card (HDD,FDD,COM etc) the device probe at boot detects the 
drive as device ft0. On switching to a Pentium m/b with embedded controller
the device is not detected. The DOS TAPE.EXE detects the tape drive in
either configuration. If I disable the embedded FDD controller and install
a separate controller card, the drive *is* detected!
There must be something different about the embedded controller!
FreeBSD cannot probe it on this controller, but TAPE.EXE can find it.
>How-To-Repeat:
M/B is a Gigabyte GA586 HX (although I suspect any pentium m/b will do it)
Boot with tape drive connected to embedded controller and compare to boot
with separate controller.
>Fix:
Install a separate controller card just for the floppy and tape drive!

The ft driver is a mess and has other problems as well (PR 1661, 1331)
