I have never trusted Windows to run my BBS reliably but I did run it
under DOS/DeskView before testing it under OS/2.

Oh what a difference. DV was supposed to be a multitasking system but
never came close to a real multitasking operating system like OS/2.

JK> 604k low memory, 2meg EMS, 8meg XMS, and the HMA is available too,
JK> DOS is loaded low. QEMM97 is good for that. And though not listed,
JK> Windows provides DPMI memory too.

This is my latest BBS memory use under QEMM97 and DV:

Memory Type         Total  =   Used   +   Free
----------------  --------   --------   --------
Conventional          640K        24K       616K
Upper                   0K         0K         0K
Reserved              384K       384K         0K
Extended (XMS)     15 360K     7 680K     7 680K
----------------  --------   --------   --------
Total memory       16 384K     8 088K     8 296K

Total under 1Mb       640K        24K       616K

Total Expanded (EMS)                 15 552K  (15 925 248 bytes)
Free Expanded (EMS)                  10 256K  (10 502 144 bytes)

Total Extended (XMS)                 15 360K  (15 728 640 bytes)
Free Extended (XMS)                   7 680K   (7 864 320 bytes)

Largest executable program size         616K     (631 008 bytes)
Largest free upper memory block           0K           (0 bytes)
Available space in High Memory Area      20K      (20 864 bytes)
PC DOS is resident in the high memory area.

-----------------------------------------------------------------

Going below 615k free did result in unreliability.

I have never had any reason to check the memory usage under OS/2.

Have a nice day,
