I've got a pentium box that has 64mb of ram in it. It's been awhile since I've messed with memory management in DOS, so I was wondering how you all would set things up to get the most usage out of whats in there. Thanks!

Example of CONFIG.SYS:

DEVICE=HIMEM.SYS (XMS/HMA memory provider)
DEVICE=EMM386.EXE NOEMS/RAM
(or DEVICE=UMBPCI.SYS)
DOS=HIGH,UMB,AUTO
FILESHIGH=30
FCBSHIGH=4,0
BUFFERSHIGH=20
LASTDRIVEHIGH=26
STACKSHIGH=9,256

Thanks for the example! Most of it did'nt work until I removed most of the 'HIGH's at the end. Perhpas its because I'm using DOS 6.22? Anywho, Everything seems pretty good now, so thanks.

Right. They("HIGH"s at the end) will only work on newer versions of DOS, like MS-DOS 7.x or FreeDOS Kernel 2032, but not on older versions of DOS like MS-DOS 6.x or FreeDOS Kernel 2029. So if you want to use "HIGH"s at the end of these commands to get even more low memory, then it's a good idea to upgrade your DOS. Here you can get some information:

I wonder, why should you use so many FCBs? They are present only to be compatible with DOS 1.x programs and it's quite hard to even find those. In other words: that's a waste of memory (not a big one, but still a waste). So best set it to minimum (which is 1 in MS-DOS 6.22).
Also: the STACKS statment. Set to 0,0 to save memory. You can make it larger if any problems do accour.
One more thing: you can use DOSMAX to get loading of STACKS, FCBS, etc, data high in MS-DOS 6.22
