When i need a 720Kb disk to be formatted on my 1.44 drive it works out
fine when i use PCTools. (LD drives can r&w)
But once i formatted the disk my drive can't read 1.44 disks until a
reboot....
Q: Can anybody give my the controllerinstructionset ?
   I couldn't find anything usefull in the IBM BIOSsource. (Ok, it was a
   M24 in the days nobody had heared of HD)
