Cross Brand - 1 MB VRAM aperture base address disabled

Applicable to: AP-S, Canada, LA, United States

Source: RETAIN tip H107321

Abstract:
1 MB VRAM aperture base address disabled

TEXT:
After installing more than 8MB of memory in a model 95XX, 85XX, you may observe that the 1 MB VRAM aperture, listed under the XGA-2 display adapter, has been disabled.

This is normal and is not a defect. No parts should be replaced.

Further information about the aperture may be obtained by using on-line help from the Change Configuration menu (F1 key).

PS/2 system video memory apertures are discussed in detail in the "Personal System/2 Hardware Interface Technical Reference - Video Subsystems" manual. This manual, S42G-2193, may be ordered on-line through Pub Order.

If 16 MB of memory is installed, the system will count less than the 16 MB. This occurs after disabling the video aperture.
