[comp.windows.ms] Windows 386 on Gateway 386/33 messes up DOS apps...

dan@rna.UUCP (Dan Ts'o) (01/11/90)

	I'm trying to use Windows 386 on a new Gateway 386/33 Mhz with a
320Mb Micropolis disk and Adaptec ESDI controller.
	I find a strange (annoying) symptom when running a standard DOS
app. such as trying to open a DOS COMMAND.COM window. For some reason
Windows tries to default the process to the A: drive (the floppy). Of
course it should default that window to the current drive (and directory).
	I have run Windows 386 successfully on another Gateway machine, a
20Mhz 386 with the same (Phoenix) BIOS, so I don't really suspect the
Gateway machine itself (but I could be wrong...). I thought it might be
the Adaptec ESDI controller. Indeed Microsoft mentions problems with some
ESDI controllers.
	Yes, I've set COMSPEC and SHELL to be reasonable. Microsoft suggested
setting virtualhdirq=OFF which doesn't help. Any ideas ? Please email. Thanks.

A friend of mine has a Gateway 386/20 -- Under Windows 386, one version of 
the motherboard has exactly the behavior that you describe.  It turns out that
the motherboard (NOT a Micronix) was at fault -- something really weird with
the DMA arrangement or something.  Also, another manifestation of this problem
is if you run a Microsoft Windows program that uses the Math emulation library
(win87em.exe) and then try to bring up a chart in Excel without exiting windows
first, the machine locks up TIGHT.  We gave up trying to software patch the
Excel hang, and he swapped for a Micronix motherboard. Gateway is apparently
aware of problems, since they offer such a swap.
