I haven't seen that symoptom, but there have been a few Minix hangs
on my machine in which CTRL-ALT-DEL resulted in a hard disk boot,
ignoring the MINIX floppy in drive A: the boot routine never looked 
at the disk (i.e., the drive motor light never came on).  A second
CTRL-ALT-DEL worked fine.  My machine is an olde, original true blue
PC-1 with the new BIOS chip to support an expansion chassis
and hard disk.
 
I've never seen this problem except following a Minix hang.  Sound 
familiar to anyone?
