sti
was created by HP to provide uniform
frame-buffer access operations for their 9000/300 and 9000/700 series of
workstations.
The following models are supported (though not all features or frame buffer depths may be available):
Model | Bits | Mem | 3D | Machines/Cards |
EVRX | 8 | 2 | HP9000/425e | |
GRX | 8g | 2 | SGC | |
CRX | 8 | 2 | SGC | |
Tomcat | 8 | 2 | SGC | |
Stinger | 8 | 2 | HP9000/7[12]5/74[257]i | |

Implementation consists of a set of functions burnt in to the PROM on the card and providing the following set of functions (see below for PROM revision history on functions supported by particular PROM revision):
There are two modes for accessing the PROM: “byte” and “word” mode. In “byte” mode each 4-byte word contains only the low-ordered big-endian byte of data; i.e., to compose one word of data 4 words should be read and low-ordered bytes of those should be shifted correspondingly. In “word” mode each word contains all 4 bytes of valid data.
