I've been booting freedos 1.0. because it's the only dos
I can find that can access large hard drives(up to 128G?).
But when I try to use expanded memory in PowerBASIC 3.5, PB
reports error 202, which is an "expansion memory error". I
understand that it's not PB's problem, but I was just wondering
if anyone understood what triggers this error in PB. I am
asking because Japheth, who wrote an excellent emm386
driver replacement based on the freedos code, has expressed
a willingness to work on his code(which exhibits the same
behavior) in an effort to make it work with PB. You can
download his version(complete with sources) at:
http://www.japheth.de/downloads/jemm526.zip
I've tried several emm drivers to try and fix this, but few
work very well with freedos. when Japheth gets his driver to
work with PB, it will certainly become my favorite because
it only uses 512 bytes of low memory and it seems to be
faster than the others I've tried(haven't done any tests
though). There's a thread on alt.os.free-dos for anyone who
is interested. Oh yes, and all I have to do to trigger the
error is dim anything virtual such as:
DIM VIRTUAL TEXT(20000) AS STRING * 10
Please help

P.S. japheth's emm driver works with msdos(others also)
so you don't have to boot freedos to try it.
