[comp.sys.ibm.pc] flushot3/JRAMIII weirdness

mvolo@ecsvax.UUCP (Michael R. Volow) (03/05/88)

On my IBMPC with JRAMIII card (1.5 meg plus SSC module) with JRAM
{drivers (jboot.bin and jdrive.bin), I recently installed flushot3
in my root/autoexec.bat in hopes of protecting against virus 
programs.  I immediately had all kinds of warnings that something was
trying to write to command.com (DOS 3.1), when my autoexec.bat was
trying to copy a few utilities to my ramdisk (using JRAM's jet.com
fast copy routine); or when I tried to do a >dir c:\command.com
command.  This did not happened when I tried >dir a:\command.com to
a write-protected, original DOS disk in drive a:.

My interpretation is that the JRAM software patches the image of
command.com in memory to get some of its unique features and that 
I do not have a virus.  Is this a correct assumption.  I did a
comp on the command.com's in a: and c: and they have the same date
stamp and length, and the end of the files look the same when I
view them with browse.com.

Your suggestions would be appreciated.  I have removed flushot3 for
the time being.
