Upgrading Video Memory (UMA)

The default setting for the video memory is 1 MB. The video memory is resident in the main memory, so if there is 12 MB of main memory, 1 MB of this is allocated to the video memory.

To increase the amount of video memory from 1 MB up to the maximum of 2 MB, there is no need to physically install any video memory modules. If we use the above example of 12 MB of main memory, this means that setting the video memory to 2 MB would leave 10 MB for the main memory.

This is useful when there is a need to upgrade the video memory for applications that will need more than 1 MB. This can then be switched back to the original setting when finished.

The video memory can be upgraded either by using the HP Setup program or from within Windows 95.
