HP OpenVMS I64 – Graphics Software Installation & Customization
ATI RADEON 7500 PCI Graphics Controller Installation Guide
Restrictions, Limitations and Defaults
This section of the document contains limitations, restrictions and defaults for the ATI RADEON 7500 hardware and software.
Minimum Console Revision
The minimum console firmware version for support of the ATI RADEON 7500 graphics controller under OpenVMS I64 is system dependent. Please consult your platform option information for minimum requirements.
No VGA Console Support
The initial OpenVMS I64 production release (V8.2) does not support the use of a graphics card (VGA mode) as a console terminal device. This is expected to be allowed in a subsequent release. A serial line console, or other Management Processor attached device is required.
HP Integrity Platform Slot Restrictions
The Version V8.2 release of OpenVMS supports three HP Itanium platform types: The RX1600, RX2600 and RX4640 (along with speed and CPU variants). The following are the known restrictions on populating slots with ATI RADEON 7500 cards:
•RX1600 – Only one slot (the top slot) allows an ATI RADEON 7500 card, the bottom slot is mechanically obstructed. Do not attempt to force a card into the lower slot.
•RX2600 – No restrictions. Up to four ATI RADEON 7500 cards may be placed in any of the slots.
•RX4640 – Up to 4 ATI RADEON 7500 cards may be used, with restrictions on the use of slots 3 and 4, and 5 and 6:
oOne card in slot 3 or 4, but not both
oOne card in slot 5 or 6, but not both
oOne card in slot 7
oOne card in slot 8
If ATI RADEON 7500 cards are plugged into slot 3 and 4, or 5 and 6, the following error message may be displayed during system startup, and the system will not function correctly:
WARNING[2]: Insufficient resources to assign one or more I/O devices
Default Depth (24 Bits Per Pixel)
OpenVMS has traditionally set the default pixel depth to 8 bits per pixel on 2D graphics options, and 24 bits per pixel on 3D options. With the expanding use of applications such as MOZILLA and increased use of various types of images such as GIF and JPEG, the default depth for both 2D and 3D has been changed to 24 bits per pixel.
NOTE: Many older applications may assume a specific depth and visual type – in particular 8 bits per pixel and PsuedoColor. If your graphics application or a utility depends upon the depth, you can either modify the application, or change the default pixel depth. For example, the PAINT program which ships on DECwindows Motif currently only support 8 bits per pixel.
For instructions on changing the pixel depth, see “Overriding the Default Settings” on page 11.
