Thank you for Jack's advice on this matter. However a patch to EMM386
[ ftp://ftp.devoresoftware.com/downloads/emm386/emms204.zip ]
would be even more usefull :)
All kinds of help do help though, even strong advices.
Now let's hope that, because of no patches were contributed by other ppl
for this, Michael or Tom can develop a EMM386 patch on his own to
(partially?) implement the advice which Jack gave.
If he's saying that we need to implement a more substantial lock/unlock,
there is no case for doing so. The lock function returns all information
related to physical memory contiguity. We explicitly flag and otherwise
indicate that internal remap and DMA buffers are not supported, as is
explicitly allowed by the VDS specification. Further, since UMB logical
addresses will never change after their initial setup, physically locking
those blocks is unnecessary.
Bottom line is that without direction information to the contrary, I do not
see any of the given information as impacting EMM386 as currently implemented.
