memory
Borealis graphics controller and 16 or 32 MB display
memory and DVI-I DVI/VGA connector. Note that the
Eclipse3CPCI and Eclipse3PCI have both VGA and DVI-I
connectors.

Coating, Extended Temperature. Rear Panel I/O (CPCI J2).
Rastergraf Borealis 2D/3D High Performance 128-Bit
Graphics Processor has vector and pixblt functions and
programmable video timing. It supports SGRAM color and
write-per-bit register functions and includes a VGA core.
The maximum supported frequencies are 250 MHz for the
pixel clock and 100 MHz for the memory clock.
Display memory is 16 MB or 32 MB of 128-bits/word, byte
addressable, no-wait state SGRAM.
16 MB of SGRAM gives eight pages of 1600 x 1200 using
8-bit pixels, four pages using 16-bit pixels, or two pages
using 32 bpp. 24 bpp packed pixel mode is not supported.
128 KB Flash EEPROM contains the Rastergraf Quad
Image BIOS (QIB) that supports SPARC FCode, VGA
BIOS, DVI, and Sync-On-Green (SOG). A user jumper
enables the QIB to select SOG.
The Borealis chip has an internal 250 MHz RAMDAC. It
has a 256 entry Look Up Table (LUT), which is converts 8-
bit pixels into full 24-bit RGB pixels. The RAMDAC has a
programmable four color bit-mapped 64 x 64 cursor. It
supports VGA and common non-interlaced displays
ranging from 640 x 480 up to 1920 x 1200. Signature
registers enable display analysis for end to end testing.
The pixel size can be 8, 15, 16, or 32-bits. For 15 and 16
bpp, the pixel is divided into Red, Green, and Blue: 5:5:5 or
5:6:5. For 32 bpp, pixel is divided into Red, Green, and
Blue (bits 24-31 are unused): 8:8:8:8.
