- /FHQ5: How can I upgrade my 80286 for best DESQview performance?/FB
-
-
-
- A 80286 can be upgraded with LIM EMS 4.0 expanded memory, a memory
- management chip, a plug-in 386 adapter, or a new 386 motherboard. The
- cost of all these ``upgrades'' is about the same. All of them have some
- negatives as well.
-
-
-
- /FL(1)/FB If you are unsure how much of your 286 conventional memory can
- disabled, getting LIM EMS 4.0 memory may not help you. For the record
- the listed 286 motherboards can be set to the minimum conventional
- memory as follows:
-
- /ML4//FLAST Premium 286/FB 0K
-
- /FLIBM AT (6 Mhz)/FB 256K
-
- /FLCOMPAQ 286/FB 256K
-
-
-
- /ML-4/Most AT clones have a minimum of 512K (eighteen 256Kx1 DRAMs). The
- motherboard can only be disabled to 256K or lower if it supports 64K
- DRAMs, or if the system setup allows you to specify a value less than
- the actual amount of memory installed.
-
-
-
- If you have information on the minimum conventional memory of any other
- 286 motherboard, please forward it to the editor /JB(see the Introduction)/CONTENTS/.
-
-
-
- /FL(2)/FB If you get a memory management chip, an All-Charge Card or a SOTA
- POP, you will still not get the memory protection available with the
- 80386 /JB(see Q4)/q4.txt/.
-
-
-
- /FL(3)/FB If you get a 386 Adapter to replace the 286 CPU chip, there has been
- ``some reported'' compatibility problems. Also, it will not run as fast
- the corresponding 386 motherboard of the same clock speed.
-
-
-
- /FL(4)/FB If you get a new 386 (or 386SX) motherboard, there is some hassle to
- get it installed and working but probably no more than with the 386
- Adapter kits.
