I have just gotten my hands on a Thinkpad 560 (the 2640-10U version)

I have upgraded the BIOS to 1.20

I wish to confirm that a 64M EDO SO DIMM (3.3V no parity) is the biggest it can
use. An e-mail I have gotten claimed a 128M sodimm might also work.

The DYKA-22110 is dying, and I tried to replace it with a DJSA-220. If I leave
the DJSA-220 is left in the machine, it will not boot a DOS 6.22 floppy. If I
remove the DJSA-220, the machine will boot.

What, if anything can I do to the Thinkpad to get ti to play nice with the 20
gig DJSA-220?

If it will never play nice, what is the largest hard drive it WILL play nice
with? The only mention of a bigger hard drive in any IBM lit. says 5 gig.
Another mentioned an 8 gig limit. Does anyone REALLY know?
