CREGFIX.COM + EMM386.EXE

Two solution exist - or make driver (.SYS version) and run it before EMM386 or make DPMI version of CREGFIX.

Checked it out. If you run this CREGFIX.SYS after EMM386.EXE in CONFIG.SYS - the above error occurs. But if you put it BEFORE it, there is no such error.

It is only half of test. Do Windows load successfully after that?

N.B. And probably you can just do such version youself if you need it: COPY /B CREGFIX.EXE+CREGFIX.SYS CREGFIX.EXE, isn't it?

On the current hardware (Without VCACHE error) - loaded successfully. For reliability, it would be necessary to check this on the problem hardware (Which is subject to this error), but I don't have it at hand at the moment.

And why did you ask solution without having problem?

I'm focusing on choosing the right hardware for the new configuration, and I came to ask if there is a solution to this problem. The choice depends on it. If there is a solution, then it will be one piece of hardware (later). And if there is no solution, then it will be a completely different hardware (earlier). Such things you want to know in advance, so as not to make a mistake and make the right choice.

no, no, no! hybrid sys+exe is not just concatenation.
when loading exe file via DEVICE= command, DOS wiill skip exe header only, not all body of exe file.
u need rewrite source for it.

It is good logic, but this problem now is minor for systems with this bug.

Ok, but i think it is not so simple for DPMI executables at all.

why even use dpmi for such simple app?

I assume just because it is relatively easy way to deal with PM environment.

or make DPMI version of CREGFIX

For test:

Added WP_OFF.EXE and as it is PM application it clears CR0.WP (Write Protect) bit only. Works with Ring 0 DPMI hosts only - as included CWSDPMI R5 and R7 versions.

Added .SYS and DPMI versions
