Happy to do that, but elgar has a single memory chunk only (on the accelerator board). Not sure what we hope to learn from that.
What about the 16 MiB on-board FastMEM? Can't we access that?

Can't see that under Linux - might have been suppressed from being passed to the kernel by use of a memfile.

There's a memfile on elgar, with the following content:

2097152
0x08000000 125829120

You'd need to enter the on-board (16 bit?) FastMEM after the 128 MB chunk. No idea what base address it would appear at.

And there is also the "Big RAM Plus" with 256 MiB RAM in elgar although
last time we tested it, Geert said it can be used as a RAM disk only
as the support for using it as RAM is not there yet.

That support still isn't there yet (though I think it should be possible to write now that we've switched to memblock). And the card doesn't appear to be installed at present? Doesn't show up in the lszorro output at least.

Cheers,

    Michael
