[comp.sys.hp] Problems with conventional memory

etna@mtecv2.mty.itesm.mx (Etna Aurora Rojas Flores) (07/05/90)

I'm working with HP Vectra ES/12 and I need to install software
that needs 639K in main memory but DOS just recognizes 636K
  How can I make that DOS recognizes 639K?

               Thank's.

Re: the need for 639K of base memory on a Vectra ES/12.  (The problem
is the same on every Vectra I've seen, including RS and QS models.)
The problem is that the top 4K of the base 640 is used for an extended
BIOS.  It is possible to turn off this extended BIOS, but you then
lose the use of HP-IL devices (i.e., the HP Mouse).  (I'm not sure
what else, if anything, you lose when you do this.)  You can turn off
the EXBIOS from SETUP from the screen you get to by typing "YADA" at
the main menu.

Run setup and type 'yada'.  This will give you an
extended menu.  Disable the extended bios(which also disables the HP-HIL
mouse).  You will then have your full 640K or memory.
