Thread: Find RAM on IBM PC

  1. #1

    Default Find RAM on IBM PC

    How do I find out how much RAM I have in my IBM PC w/ PC-DOS 3.1?

    Put a DOS 5.x or 6.x in and use MEM.
    If you're looking for DS/DD or DS/HD 3" or 5" floppy disks, PM me. I've got some new, used, and factory over-labeled disks for sale.

    chkdsk should give you what you want.

    Can't do that. Don't have 5.25" copy of anything later than 3.3, or a disk drive that could write it.

    Use CHKDSK as Mike said.
    It reports the total and free memory in the system (as well as checking your file system).

    Code:
    A>debug
    
    -a100
    2E68:0100 int 12
    2E68:0102 int 3
    2E68:0103
    -g=100
    AX=0280  BX=0000  CX=0000  DX=0000  SP=FFFE  BP=0000  SI=0000  DI=0000
    DS=2E68  ES=2E68  SS=2E68  CS=2E68  IP=0102   NV UP EI PL NZ NA PO NC
    The value in AX is the size of memory in kilobytes (so AX=0280 means 280h, 640 decimal).

    Does CHKDSK v3.1 actually supply memory info?

    Apparently so.

    Thomas Byers (DRI)- "You'll have a million people using the A> [MS-DOS prompt] forever. You'll have five million using [nongraphic] menu systems such as Topview, Concurrent PC-DOS, Desq, and those types. But there'll be 50 to 100 million using the iconic-based interfaces."

    I hadn't thought about that, but every time I haven't had MEM, CHKDSK has been there and given me the answer.

    CHKDSK reports 640KB. No need to upgrade this puppy!
