Intel MB440LX manual PCI Expansion Slots, PCI Video Controller

PCI Expansion Slots

The seven PCI bus master slots on the system board provide for expansion and performance enhancement. One of the PCI connectors shares a common chassis I/O expansion slot with an ISA connector; you can use either PCI or ISA in the slot, but not both.

The PCI bus operates at up to 33 MHz and provides

∙32-bit memory addressing

∙Support for 5 V and 3.3V cards

∙Burst transfers of up to 133 MB per second

∙8-, 16-, or 32-bit data transfers

∙Plug and Play configuration

∙Hierarchical bus to maximize connectivity

PCI Video Controller

The onboard Cirrus Logic CL-GD54M40 32-bit video graphics accelerator contains a super video graphics array (SVGA) controller that is fully compatible with these video standards: CGA†, EGA†, Hercules† Graphics, MDA†, and VGA. The standard server configuration comes with 512 KB of onboard video memory allowing pixel resolutions of up to 1024 x 768 and 16 colors.

The SVGA controller supports analog VGA monitors (single and multiple frequency, interlaced and noninterlaced) with a maximum vertical retrace interlaced frequency of 87 Hz.

The buffer size of the onboard video memory can be increased from 512 KB to 1 MB with one 40-pin 256 K x 16, 60 ns fast-page dynamic random access memory (DRAM). 1 MB of DRAM will allow the controller to support

132-column text modes and high resolution graphics with 1280 x 1024 x 16 colors. Depending on the environment, the controller displays up to 64,000 colors in some video resolutions. It also provides hardware accelerated bit block transfers (BITBLT) of data.
