 PH> Organization: Surely you jest

 PH> I have an Intel SnapIn 386** installed in an old IBM PC-AT with 640K+3M,
 PH> 1.2 and 360 floppies properly configured in CMOS, and at the moment a
 PH> pair of MFM hard drives (which I'm planning to replace with an ESDI).
 PH> Can anyone think of a reason why 386bsd should not at least boot on it?

 PH> It will clearly not be a terribly fast system, but so far, I have not
 PH> been able to find a 386bsd boot floppy which will work on it at all.
 PH> I usually get the floppy-light-stays-on problem which others report
 PH> having solved by bouncing on numlock.  (I've tried that, too.)

 PH> ** For those who may not be familiar with it, the SnapIn 386 is a small
 PH>    assembly which contains a 386SX-20 with 16Kb cache.  It plugs into
 PH>    the AT motherboard in place of the 286 processor chip, thereby
 PH>    upgrading the machine to a 386SX.  I have the cache disabled.


     Do you have a 287 math cooprocessor installed? Without the dos driver  
you have no cache avaialable, However you do have the straight 386. Intel  
upgraded the 287"L" if I remeber right with a 287 that would support the  
386 command set. Without the upgraded 287 your Snapin is limited on it  
support.
