- Subject: Blums's UMB driver and huge free RAM for NB
- Newsgroups: bit.listserv.notabene
- Lines: 87

- More news re Blum's driver:
-
- On my 386 computer, with C&T 82C351 ( 386DX ) chipset (4M RAM), and
- a) forcing the shadowing of A000- in the /M switch (which
- apparently removes some of my video shadowing, but NB doesn't
- care)
- b) using the "extended" version of the Hyperware cache--Hyperdkx,
- not Hyper386
- c) enabling all shadowing in the BIOS setup, _except_ for 64K
- system ROM (F000-), the results for NB are:
-
- When I first enter NB, it reports 380 Kb free; after a Shell to
- DOS and return, it reports 402 Kb free; after using "func me" (or
- Itamar's or Tony's utils) to remove the Math, Spelling, Sorting,
- and Printing files, it reports 429 Kb free--while maintaining a
- complete HELP_ file. This is spooky, but apparently it works.s.
-
- This configuration, however, is useless for Windows
- (total garbage results), and ineffecient in freeing up the
- complete amount of memory for EMS, as the following report shows.
- I'm still working on the Windows set-up (I now can have the Video
- OK--i.e., no freeze-up--but it looses the boot-page). Re-booting
- w/ an alternative config and autoexec (there are utilities that
- facilitate this) seems at the moment to be worthwhile, given the
- dramatic results re NB alone (my first and true love).
