NOTES ON FLUSHOT3:
FLUSHOT3 is an enhancement to FLUSHOT2. A bug was fixed which could have
caused certain weird things when you denied direct disk I/O to certain
portions of DOS 3.x. This has been fixed.
Please read this next note carefully:
SIMPLY BECAUSE THE FORMAT COMMAND, OR A DISK REPAIR UTILITY, OR SOME
OTHER LOW-LEVEL DISK PROGRAM TRIGGERS FLUSHOT, IT DOESN'T MEAN THAT
YOUR DISK IS INFECTED! SOME PROGRAMS LEGITIMATELY HAVE THE NEED TO
DO SOME LOW-LEVEL WORK!
This means that when you do a "COPY *.* B:" or something and cause a new
COMMAND.COM to be created on your B: drive, FLUSHOT will be triggered. It
does not mean that you should suddenly call me up at 3 am to ask a very
groggy person what to do next. You might not like the answer you get! :-)
The enhancements to FLUSHOT3 include the ability to enter a 'g' when FLUSHOT
is triggered. This will cause FLUSHOT to become inactive until an exit is
called by the foreground task. So, when you use some trustworthy program
which does direct disk I/O, you won't be pestered with constant triggering
after you enter the 'g'.
Additionally, your CMOS ROM is checked upon every DOS operation against
the original value it had when you first ran FLUSHOT. If there is a
difference, you'll be advised, and have the option to restore the original
CMOS memory.
What the heck is CMOS memory, you might be asking. Good question. In AT
class and beter machines, certain important parameters (such as the type of
hard disk you're using, or how much memory there is in your machine) are
stored up in special non-volitile memory, called CMOS.
If this gets changed, you might have a problem when you reboot. FLUSHOT3
sends at least one little slimebucket back to the drawing board, because
it will restore the CMOS and prevent this hassle from occuring.
Additionally, you now have some options in FLUSHOT3:
FLUSHOT3 [-D][-F][-C]
-D - Do not monitor direct disk writes (int26)
-F - Do not monitor direct floppy writes (int13)
-C - *Do* check CMOS - AT class and better only
the default installation does *not* check CMOS
As in the other FLUSHOT programs, please be sure to upload any suspect
programs to my board at (212)-889-6438 (24 hr, 2400/120/300 N81), as well
as any suggestions, enhancements or bug reports. You can also reach me
on BIX as 'greenber'.
