Jemm v5.69 ... (Announce)

will hopefully fix everything!

It can be found at http://www.japheth.de/jemm.html

changes for v5.69

- memory block copies are now done with interrupts enabled - if client's
interrupt flag is set. This avoids interrupt latency and makes the
previously implemented "interrupt windows" obsolete. It also avoids
problems with Jemm's HLT emulation causing IRQs to be misinterpreted
as exceptions (08, 09, 74, ...) on some cpus.
- bugfix: VDS scatter/gather lock with region size 0 returned 0 entries,
but 1 entry must be returned in any case (MS Emm386 does as well).
- bugfix: there was a risk that a ROM located contiguously behind another
ROM in address space wasn't detected.
- bugfix: if SPLIT option was set and a split ROM page followed an UMB
page (which is possible if ROM size is < 4 kB), the ROM part of this
page was added to the UMB.
- bugfix: synchronization of VCPI and EMS free memory count did work
for VCPI only, that is, allocating all VCPI memory didn't reduce free
EMS memory to zero.
- bugfix: the last XMS memory block allocated for EMS/VCPI memory was
likely to be too large, thus wasting XMS memory.
- VCPI/EMS memory alloc/release speed-up.
- EMSSTAT -v displays more VCPI infos.
- v86 exceptions >= 8 are routed to v86 interrupt 06h only if this vector
has been changed by another program.
- evil exception 10h (floating point) is now detected and displayed, thus avoiding
the hazardous call of video interrupt 10h (MS Emm386 also detects
exception 10h, but just allows to reboot then).

Well, the changelist looks really impresive.

I was more talkative (using the "Auer" style :-D ), but if the old version worked well for you, there won't be much difference.

Yes, work as good as before :)

Yes, of course, if you like those displays ... :-D

Seriously, I don't know, but IIRC I already mentioned that you should try to improve the quality of your "bug reports".

There has an int 3 opcode (CCh) been forgotten in the EMSSTAT.EXE binary, which is executed if EMSSTAT is launched with option -v. Usually such an Int 3 does no harm at all, but you have a SB PCI driver loaded, which does some strange things: it transforms an int 3h to an exception 0Dh with error code 1Ah (I don't know why). Jemm knows option "SB", however, which has been inherited by FD Emm386 and which should neutralize this strange behavior.

Yes, with "SB" run right.

thanks.
