OK, more questions.  My boot disk uses DJGPP, which needs a DPMI
provider.  I also need to maximize the free conventional memory
(winnt.exe uses a lot), so I also want to have an XMS (or is that
HMA?) provider and a UMB provider.

At the moment, I am using himem.exe, umbpci.sys, and cwsdpmi.  I have
read that the customary UMB provider is emm386.exe, but for some
reason it seems to be incompatible with cwsdpmi.

(By the way, I am just throwing terms around here without really
understanding most of them.  DOS memory management is still largely a
mystery to me.)

Right.  So here are my questions.  First, is there some better
combination of utilities I should use?  Second, what am I losing,
exactly, by using umbpci.sys instead of emm386.exe?  And finally, how
come cwsdpmi doesn't work with emm386.exe?

Thanks!
