The DECchip 21030 PCI graphic accelerator allows the EBVXG graphics module to offer the following features:
• Support for a wide range of monitor resolutions, resulting from fullyprogrammed video timing and an ICS 1562 phase-lock loop (PLL) video clock generator.
• Support for several graphics modes, including accelerated mode and simple frame buffer.
• Implementation of a 2D and a 3D graphical user interface (GUI)
• Large-scale integration single-chip accelerator.
• Unique frame buffer configuration built on a high-speed 64-bit memory bus.
• Patented dithering algorithm (AccuLook) giving 8-bpp images the simulated appearance of 16-bpp (high color) images.
• Nominal fill rate to screen higher than 640 Mpixels/s.
1.4.4 Bt485 RAMDAC
The Brooktree Bt485 RAMDAC chip is connected to the DECchip 21030 PCI graphic accelerator and the 8-bpp frame buffer.

2.3 Switches
2.3.1 SW: Monitor Type Setting
SW is a switchpack on the EBVXG graphics module. See Figure 2–1 for the on-board location of the switchpack (SW).
The switches are used to set the monitor type. The firmware determines the monitor resolution and timing by reading the switch setting. Since the switch settings cannot be accessed from the system I/O panel, be sure that the switches are set correctly before you install the EBVXG graphics module.
See Table 2–2 for the switch settings. The switchpack consists of eight switches; only the first four switches are used for setting (Figure 2–3). Each switch corresponds to a binary (0 or 1) place in the table. All zeros to 1111 is equal to 0 to 15 decimal combinations. The EBVXG is shipped with all these switches set to
0000 (all 0s).
