I think my TL/2 is unable to run himem.sys.
Is this a limitation of the TL/2 architecture? I've tried every flag for machine type with "himem.sys /cpuclockn /machine:#" with no luck.
I recently upgraded it to 768k of ram, but I believe that it just ends up getting used for video ram (freeing up more conventional ram below 640k).
Is the TL/2 incapable of using more than 640k of conventional ram? What is the use of the 2MB EMS card? Will Windows see it with the LTEMM.exe?

II.A.4. How do I add additional expanded memory to my system?
On older 1000's (i.e., pre-SL) with standard slots, four EMS cards will work: the Micro Mainframe 5150T, the Intel Matched Memory Classic, the Intel Above Board ISA, and the InvisiSOFT Invisible EMS board. The latter three are hardware LIM 4 and can be used for upper memory blocks with DOS 5 or 6 (possibly requiring Qram or equivalent); the 5150T does not supply upper memory blocks. Upper memory blocks may not be available on systems with DOS in ROM, even if DOS is upgraded, because the memory segment (E0000h) that would be used as an upper memory block by the EMS card is already occupied by the ROM drive (whether the ROM drive is accessed or not).
A few multifunction cards were made for the original 1000, A, and HD that had expanded RAM as an option. The PBJ XRAM card was another EMS card that would work in those systems.
The EX and HX will need a special EMS card because of their nonstandard slots. (With those systems, conventional RAM and EMS may be added on the same card.)

Some years ago I put an Intel expanded memory board in my TL, but I had a heck of a hard time getting the Intel software to configure the board to the computer. I called Intel and although they they tried, they couldn't help me. Because the TL has an 80286 processor, the software tried to make the computer out as an AT clone. But when the software sensed the 8 bit expansion slots, it was sure the computer was an XT clone. Therefore I couldn't configure it as an AT nor as an XT. However out of frustration, I tried configuring the TL as an IBM model 30. That worked and the board has been working ever since.
The SL's, TL's, RL's, and RLX's can use any 8-bit expanded memory card that is 10" or less in length. The RSX's do not need expanded memory; use extended.
