On an old 5150, you'll only have 64KB or 256KB RAM in a stock machine.

I ran 3ccfg.exe on my 5150 with 256KB, and the program said there was insufficient memory.

I added the RAM extension for the XT-IDE, configured to 640KB, and then 3ccfg is working.

why does 3ccfg need so much RAM? I am not sure if the 3c509.exe also needs this much RAM -- if it turns out 3c509 driver needs this RAM for TCP/IP or whatever buffers, then that's fine - no issue then.

But if 3c509 can work with 64KB or 256KB, maybe the CONFIG utility should also try to work within that constraint.

I didn't try running 3ccfg from command line to see if it can complete the configuration with less memory. I know the readme notes give the suggested command line parameters - but I have to run 3ccfg to verify/examine what all those options are. But now I realize the suggested options in the readme are probably ok for like 99% of the situation.

Anyway - this same problem is with MS/DR DOS newer than version 4.0. Their SETUP/install require over 256KB, but then to actually boot after the install, you can boot with regular 256KB.

Hello, while trying to download the 3ccfg.exe it leads to a 404. This is in the readme btw
