2.4.2.4 Graphics Adapter
Currently, the only graphics adapter supported by the RS/6000 Model E20 is the
IBM PCI S15 Graphics Adapter (feature #2657). Moreover, only one PCI S15
adapter is officially supported in the system.
Note: We successfully tested two S15 graphics adapters in a system. Refer to
5.6.4, “Multiple Adapter Support” on page 96 for more information.
The IBM S15 Adapter is a high-performance Video RAM (VRAM) based PCI
graphics adapter with integrated video co-processor for use as a premium graphics
solution. The adapter comes in a 2 MB fixed version. It supports the standard
15-pin D-shell (DB-15).
Table 5 on page 25 shows the supported monitors.
