[comp.sys.ibm.pc.misc] Extended Memory Problem

fritz@urz.unibas.ch (10/11/90)

Hi

I have an AT 286 with 640 k main and 3.4 M EXTENDED memory.
I use this extended memory as a ramdrive (RAMDRIVE.SYS / MS-DOS 3.3).

Recently I tried to run LOTUS V.3 without removing the ramdrive from
my extended memory --- IT WORKED !  But afterwards, the complete ramdrive
was destroyed. This always happened, also when the size of the ramdrive
was very small (so there was a lot of unused memory).

Is there any way to protect my ramdrive against destruction by
memory-demanding software?

Is this problem solved by MS-DOS 4 (I know that it is solved by WINDOWS...) ?

Thanks a lot

(please e-mail)
