OK, I tried this. If I set it to 800M it was OK. At 900M I got the same
problem.
Due to the nature of the replies I have been getting, I suspected that
the problem was with the IDE driver's initialisation. So I disabled the
"Use PCI DMA by default" option in the kernel.
It booted with the full amount of high memory. Not only that, but
"hdparm -X66 /dev/hda" after booting also works!
I can only conclude that there must be a bug in the IDE initialisation
code for this board. Thanks for the replies,
Ed-T.
