folks,

	thanks for the suggestions and clarifications.

	however, am i incorrect in my assumption that
	i can from another (2.2.5) machine rebuild
	the boot floppy w/o bounce buffers (and w/o any of 
	the isa controllers that depend upon it) ?

	(in this case, internal access to the machine is
	the choice of last resort).

	btw, if i recollect correctly, i upgraded this
	machine from 2.2.1 to 2.2.2, all with the 1gig
	installed (2.2.2 just couldn't see the whole
	gig until i modified the kernel configuration
	and rebuilt).

	also, as a generic workaround, it would probably be
	usefull if at boot time i could say something like:

		boot: fd(0,a)/kernel -c MAXMEM=16384K

	thx,

		-elh
