I used memmap=3K$637K to avoid the 3K segment just below 640K (which my BIOS diagnostics told me was reserved), with no luck. I bumped that up to memmap=30K$610K (lots of padding), also without luck. Similarly, I have tried: memmap=240M at 16M (no luck) And mem=240M at 16M ( no luck) as there seems to be some varying opinions on the 'net as to which of those is correct syntax. Of course, I might be wrong about the base cause in which case none of this is relevant ;-) Ta, Craig ======================================================================= Attention: The information contained in this message and/or attachments from AgResearch Limited is intended only for the persons or entities to which it is addressed and may contain confidential and/or privileged material.
