RE: TP360 emm386 memory range exclusion for Megahz modem

[NELSON Tim <tnelson@shl.com>]

I do the following in EMM386 to get more memory:

I=E000-E5FF

     I can include this because this part of the IBM reserved for BIOS area 
is free on my TP750Ce.  I also had a TP750C with the older BIOS, and I could 
use from E000-E6FF.  Try it.  The worst that can happen is you hang on 
startup.

X=C800-C9FF

     I hacked this out using microsoft's diagnostics (\WINDOWS\MSD.EXE) to 
look for ROM, and I found that when I told SETMHZ to place the modem at 
address C800, it worked... even though I had physical ROM from my Roland 
SCC-1 card at CA00-CEFF.

I send this message to you now, with WFW 3.11, IBM EZ-PLAY drivers, 
Megahertz XJ1144, and in my CONFIG.SYS:

DEVICE=C:\WINDOWS\EMM386.EXE I=E000-E5FF X=C800-C9FF
...
DEVICEhigh=C:\THINKPAD\DICRMU01.SYS /MA=C800-C9FF
...

NOTE: The MHZ modem is the only PCMCIA device I use currently.

Enjoy.

    Hey, all......

        I'm a new TP360 owner who is struggling with insufficient
free conventional memory.
        As configured from the factory, my EMM386.EXE exclusion parameter
looked like this: x=C800-CFFF.  This seems like a pretty big chunk of
upper memory, and since all I use is a Megahertz 14.4 fax/modem, I was
wondering if anyone had a suggestion for reducing the size of this
exclusion parameter.
        Is there a smaller range that I can use specifically
with this modem?  IBM tech support suggested using the same range
which is recommended for an IBM fax/modem (x=C800-C8FF), but
couldn't guarantee whether or not it would work.  I'm not opposed
to experimenting a little, but this trial-and-error technique that
I've been using is getting me nowhere fast!  BTW, I've tried using
Ramboost, but without much luck.  Running Ramboost with such a large
exclusion parameter doesn't leave it much space in upper memory to
work with.  As a result, most TSR's and drivers wind up being loaded
in conventional memory.
        If any of you TP360 owners have some advice, I'd sure
appreciate it if you could share it with me.  All you TP750 owners
feel free to jump in as well, as I think the two machines are
similar enough that the values may be interchangable.

        Thanks a bunch.....
