Microsoft did not provide a GUI front-end for the configuration of the vcache so we'll have to go manual on this.

First of all, you'll need to use a text editor like Notepad to open up the System.ini file. This is usually located in your Win95/98 directory.

You should see the following screen :-

Scroll down until you see the line [vcache]. Usually, there will be nothing under this line. To adjust the vcache settings, you'll need to add the following lines below the line [vcache] :-

MinFileCache=xxxx
MaxFileCache=yyyy
ChunkSize=zzzz

where xxxx is the minimum size of the vcache in kilobytes (KB)
         yyyy is the maximum size of the vcache in kilobytes (KB)
         zzzz is the granularity of the vcache in bytes

Save any changes that you've made to the system.ini file, close Notepad and reboot the system. The changes will only take effect after you reboot the system.
