Add-in board slots

The baseboard has one ISA slot that is full-length if the wide SCSI-B slot is not used (and half-
length if the wide SCSI-B slot is used); the ISA slot supports slave-only boards and is shared with
PCI-B slot 4. The ISA has three embedded devices: the Super I/O chip, Baseboard Management
Controller (BMC), and flash memory for system BIOS.
ISA features:
Bus speed up to 8.33 MHz
16-bit memory addressing
Type A transfers at 5.33 MB/sec
Type B transfers at 8 MB/sec
8- or 16-bit data transfers
Plug and Play ready
The baseboard has two 32-bit PCI bus segments: PCI-A and PCI-B. These provide seven slots for
PCI add-in boards: three on PCI-A and four on PCI-B. PCI-B4 is shared with the ISA slot.
PCI-A1 supports half-length boards only. The other slots support full-length boards.
PCI features:
33 MHz bus speed
32-bit memory addressing
5 V signaling environment
Burst transfers of up to 133 MB/sec
8-, 16-, or 32-bit data transfers
Plug and Play ready
Parity enabled
Video
The onboard, integrated Cirrus Logic CL-GD5480 64-bit VGA chip contains an SVGA controller
that is fully compatible with these video standards: CGA, EGA, Hercules Graphics, MDA, and
VGA. The standard system configuration comes with 2 MB of 10ns onboard video memory. The
video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7 M colors.
The SVGA controller supports analog VGA monitors (single and multiple frequency, interlaced
and noninterlaced) with a maximum vertical retrace noninterlaced frequency of 100 Hz.
You can not add video memory to this system. Depending on the environment, the controller
displays up to 16.7 M colours in some video resolutions. It also provides hardware-accelerated bit
block transfers (BITBLT) of data.
