I don't know that vcache has anything to do with the SCSI connection but
then with Windows it might. It does have to do with memory error messages
with RAM of over 512MB (not your situation) and a starting point for your
answer might be at
It refers to several other articles and provides MS's cryptic keywords for
further search on the topic.

Subject: filmscanners: SS4000, Win98 and VCache settings
| I use an SS4000 on a SCSI connection with a Win98SE 933 PentiumIII and
| I was having some problems with the system doing a reboot in the middle of
| scanning a transparency, usually with Polacolor Insight. I posted that
| a couple of weeks ago and got some suggestions.
| I also use my computer for speech recognition software (not at the same
| time, of course). In the process of tweaking the computer for better
| recognition, I made some changes in the Vcache settings.
| After making those "improvements," I was unable to scan a single slide
| without the system suddenly rebooting. It seems there is a connection
| between these Vcache settings and the problems I have had.
| Does anyone have experience with tweaking the Vcache settings for a SCSI
| slide scanner? I have used a couple of the shareware type programs that
| suggest values for "power users" and "multimedia" and "low memory
| I just changed the settings in system.ini to:
| The settings I had been using were min=0, max=131,000 (that was
| approximate--it was a correct multiple) with chunk size specified as 4096.
| Now I can finish a scan, but I have no clue what the optimum setting
| be, or if it should be specified at all.
