It must be something in your setup.  I have a 486 with a 1542B and have been
running DOS 5 with the UMB's for quite some time now.  I don't have the
config.sys here to simply post, but (roughly) the order of loading things
goes like this.  The following are loaded normally (device=)

	adaptec.sys	(moves the configuration tables)
	himem.sys
	emm386.sys
	aspi4dos.sys

then these get loaded high (devicehigh=:

	smartdrv.sys
	ramdrive.sys

etc.  Be sure you use the versions provided with DOS 5 and not older ones.
The adaptec.sys is very old (but small and apparently doesn't do much after
it loads); the aspi4dos.sys I have is 2.1B (beta) -- See Roy Neese's offer
posted in another article if you don't have it.

I also have the obligatory VirtualHDIRQ=False in the [386enh] section for
Windows, the net resulting setup has been extremely stable.  A sequential
file I/O test on 8MB files (4MB cache, so it gets defeated) and 16384 byte
blocks shows in excess of 500K bytes/sec write and > 450K bytes/sec read.
