Powerbasic, Memmaker and Remoteboot

[Rick Holcomb]

Well the subject line says it all. I have my new compact computers
remote booting from an NT server, it was fairly simple (yea right).
Now my problem is available memory. My application wrote in Powerbasic
is running fine as a stand alone application but I can't run it
via the IDE. I can edit and compile it but I am about 35K short
when trying to run it from the IDE. I can't use memmaker to free
up any memory because memmaker won't run from a network drive
(remote boot drive).
Remote boot uses Lan Manager to give me the connectivity I need to
share the network drives but takes up much more memory than the
DOS Client for NT networking I have been using. Here is a memory
layout as printed from the problem workstation:


Modules using memory below 1 MB:

Name Total = Conventional + Upper Memory
-------- ---------------- ---------------- ----------------
MSDOS 14,381 (14K) 14,381 (14K) 0 (0K)
HIMEM 1,168 (1K) 1,168 (1K) 0 (0K)
EMM386 8,368 (8K) 8,368 (8K) 0 (0K)
COMMAND 2,928 (3K) 2,928 (3K) 0 (0K)
MINSES 1,904 (2K) 1,904 (2K) 0 (0K)
NETWKSTA 43,216 (42K) 43,216 (42K) 0 (0K)
ENCRYPT 2,128 (2K) 2,128 (2K) 0 (0K)
RPL$ 97,168 (95K) 97,168 (95K) 0 (0K)
Free 483,936 (473K) 483,936 (473K) 0 (0K)

Memory Summary:

Type of Memory Total = Used + Free
---------------- ---------- ---------- ----------
Conventional 655,360 171,424 483,936
Upper 0 0 0
Reserved 393,216 393,216 0
Extended (XMS)* 65,011,712 540,672 64,471,040
---------------- ---------- ---------- ----------
Total memory 66,060,288 1,105,312 64,954,976

Total under 1 MB 655,360 171,424 483,936

Total Expanded (EMS) 4,423,680 (4,320K)
Free Expanded (EMS)* 4,128,768 (4,032K)

* EMM386 is using XMS memory to simulate EMS memory as needed.
Free EMS memory may change as free XMS memory changes.

Largest executable program size 481,600 (470K)
Largest free upper memory block 0 (0K)
MS-DOS is resident in the high memory area.

I have tried configuring the machine with the NOEMS switch but
that doesn't help, it frees up conventional memory but then I can't
run Powerbasic at all. Anybody have any suggestions. Here is my
current config files:

The first thing you need to do is to put your HIMEM and EMM386
lines as the first two lines in your CONFIG.SYS file.
After that, use DEVICEHIGH in your config.sys and LOADHIGH
or LH in your AUTOEXEC.BAT file to move as many files into
the upper memory block as possible. Don't worry about overloading
the UMB. If a file won't fit, it will automatically be loaded
in the LMB. This should free up a LARGE amount of memory.

I believe the boot sequence will load himem first no matter
where it is in the file. I should have pointed out that the mem
command shows that there is no upper memory available. It says DOS
is resident in upper memory but that is it. I tried the devicehigh
statement in config.sys but without any upper memory available
I'm stuck. I tried the noems switch for emm386 and it then gives
me upper memory but Powerbasic will not start at all. I guess I'm
trying to get both EMS and upper memory, maybe that isn't possible.

It's perfectly possible to get both EMS and upper memory in most machines. Unfortunately, Microsoft seems to have buried the documentation on this stuff... anybody got an old DOS 5.0-6.0 manual?

Try adding the RAM parameter to emm386:
device=emm386.exe RAM 4096 (see also : help emm386.exe under MS-DOS)

Indeed you can use the 'RAM' option to get both EMS and UMB (or simply use QEMM).
With UMB available I use "LH PB.EXE" to launch the PB editor and it gives me
lots of extra conventional memory in the IDE.
