Does D410 support Expanded Memory (EMS)?

Some modern computers don't support Expanded Memory (EMS), but I need it to run some old DOS programs I use. I'm thinking of getting a Latitude D410 (after giving up on an Acer that did not support EMS), and I was wondering if some kind soul who has a D410 could check for me if that model supports Expanded Memory.

Here's how:

Go Start > Programs > Accessories > Windows Explorer

Navigate to the C:\WINDOWS folder.

Find the file _DEFAULT (it will show as an MS-DOS icon, and should be the first file in the folder AFTER all the subfolders).

Right click, select Properties, go to the Memory tab, and select "Expanded (EMS) memory", and 1024 from the drop down list, then select OK.

Next, bring up a Command prompt by doing Start > Programs > Accessories > Command Prompt

At the prompt, type: MEM /C

If EMS is actually working, you should see a display like this (at the very end of a long display of memory info):

1048576 bytes total EMS memory
1048576 bytes free EMS memory

16777216 bytes total contiguous extended memory
0 bytes available contiguous extended memory
15580160 bytes available XMS memory
MS-DOS resident in High Memory Area

(Don't forget to go back and set "Expanded memory" back to "Auto" (the default value) in _DEFAULT after doing the test.)

As I say, I'd be very grateful if someone would run this test for me. Many thanks!

All best wishes.

Rob

Largest executable program size : 581216 (567.6K)

1048576 bytes total EMS memory

1048576 bytes free EMS memory

2097152 bytes total contiguous extended memory
