Error Memory trouble in DOS

Background Info: I have an old hard drive(210MB) that already has MSDOS 5.0 and Win 3.1 on it.
I put it in a computer that has 72MB of RAM, and a 166Mhz processor.

Problem: Some games I try to run say there's not enough memory!

Example: Day Of The Tenticle(a game) gave two different messages when I ran it.
message 1: "WARNING: Memory low, suggest aditional 33K."
message 2: "WARNING: EMS detected less than 2 megabytes."

Trouble shooting:
I fixed the second message by changing a line in the file CONFIG.SYS.
Command line edited in CONFIG.SYS: "DEVICEHIGH=C:\WINDOWS\EMM386.EXE 30000 RAM"
So now it uses about 30MB RAM as EMS.

My game still asks still asks me to add 33KB more memory when I try to run it. (unless I remove the RAM paramiter from the command line "DEVICEHIGH=C:\WINDOWS\EMM386.EXE 30000". Then it asks me to add 57K)

The RAM paramiter is supposed to fill the high memory with UMB(upper memory blocks), so I guess I need to find a way to use more of the memory I have for UMB.

Does anyone know a way to use Extended memory for UMB?

Or does you have any other ideas?

Extended memory is what the bios says I have 72MB of.

the problem is usually that DOS doesn't understand things over a certain size. eg: if you have a 1GB drive it would think it was ~200mb, since it does not understand anything larger. It was not thought that DOS would still be used once newer computers existed.

You are likely running win95 on the new computer? Either way this will probably help you out: memory allocation
