If you encounter a BIOS generated 'VIRUS WARNING' when upgrading your
operating system to WIN95/98 the cause could be any of the following:

- try hitting the f8 during the boot up and go to the dos prompt,
  then go to WIN95 and see what happens...if it does work then there is
  a problem in the set up files themselves.
- if you cannot get WIN95 to install because of the warning type setup/?
  for the other options and there is one for no will
  install the files then you will have to add the hardware drivers
  and stuff after manually.
- is the WIN95 a full version or the upgrade and is it on disk or cd.
  If on disk they had a lot of problems with Ver:A of both series.
  The 'B' version is more revised with less problems...if someone has
  tried to tamper at all with the disks then it will come up with that
  warning....they are formatted to 1.77meg on purpose to make it harder
  to hack...but it still can be done... :-)
- another way is to copy all the disks into one directory leaving the
  cab files as cabs then run this from the dos prompt.
  If they have been hacked or tampered with whether disk or cd this
  usually gets around it since it is reading itself and not another
  drive so error correction is at a minimum level...hope this helps.

- Disabling Award BIOS v4.50g Virus Protection
  This webpage explains the full procedure if you have this bios.

- and finally your BIOS's external cache might be incompatible.
  Most 32bit OS's advise disabling all external caching during install
  on older boards.  The problem resides in the older BIOS versions.
  Some M601 mainboards will not support WIN95's caching system with any
  BIOS dated 1993 or older. Try to disable/remove the onboard cache or
  buy a newer bios, BUT, try all the above procedures first.
  Once WIN95 is installed try enabling/installing the cache and reboot.
