Are you struggling with memory limitations, especially while setting up networking on your DOS system? Not only drivers and TSRs, but also network stacks can consume lagre chunks conventional memory, making it a challenge to leave enough room for your applications.

In this video, I'll show you some memory optimization techniques for DOS 6 using manual methods, but also the onboard tools that came with MSDOS, PCDOS and DRDOS, notably MemMaker, RamBoost and MemoryMax.

Of course, no way around about 3rd party memory managers. See how much you can squeeze out using products like QEMM, 386MAX and NETROOM.

And if that's not enough yet, what about using modern alternatrives to drivers and TSRs, to squeeze out even the last byte?
