中国DOS联盟

I've got another trouble in my system memories.
I've try to see my memory remains. But it may causes some errors.
First time I've see the Convential Memory is 481KB, and see the classify data is unknown reason for me. Approx 140KB in my system reserves. (Is it sure my old system is only for 500K Low Memory? (DOS=HIGH,UMB is loaded)
And I've tried 386MAX, but it only reduces into the 94KB without UMB.
Who can give a better memory manager?

What a pity you are send up here!
Are you ask about MSDOS or others? I cannot believe you are stilll use DOS from your issue! Is it working under the VM / VPC!
Do you have used an AntiVirus software's scanner to scan whether they have virus?
list here for all the details of the accident!
To try use a pure DOS boot to play the game again!
