DELL PowerEdge 4100 mainboard|
The DELL PowerEdge 4100 mainboard only supports 180 or 200MHz Intel Pentium Pro (socket 8). The PowerEdge 4100
features two on-board data caches for transferring information to and from the processor. These caches are known as
the L1 and L2 caches. The PowerEdge 4100 L1 cache is 64 kilobytes in size, while its L2 cache is rated at either one or
The PowerEdge 4100 systems have a minimum of 64 MB of 72-bit-wide, buffered EDO memory. The system memory
capacity can be expanded to 1024 MB by using combinations of 32- and 128-MB buffered, EDO dual in-line
memory modules (DIMMs) having 168-pin gold connectors. The modules must be added in like pairs to take advantage
of memory interleaving.
The video controller is connected to the PCI local bus. The standard video subsystem contains 1 MB of
DRAM memory (not upgradable). Maximum noninterlaced resolutions are 640 x 480 pixels with 16.7 million colors or
800 x 600 pixels with 65,536 colors or 1024 x 768 pixels with 256 colors.
Integrated SCSI Controllers
A built-in Adaptec 7880 Ultra/Wide SCSI controller provides an ultra-wide fast SCSI interface via a 68-pin connector
on the system board. This SCSI controller attaches to the PCI bus to provide a high-performance SCSI bus and also
controls the six SCSI hard-disk drives. In the standard Dell PowerEdge 4100 system configuration, the Ultra/Wide SCSI
host adapter on the system board controls the SCSI backplane board. When used in combination with an optional
PowerEdge Expandable RAID Controller host adapter card, the SCSI backplane board allows you to remove and insert
harddisk drives without shutting down the system. External hard-disk drives are not supported by the built-in SCSI
A built-in Adaptec 7860 Ultra/Narrow SCSI controller provides a SCSI interface via a 50-pin connector to the CD-ROM
drive and to any other SCSI drives.
The PowerEdge 4100 has two 32-bit expansion buses. The first is a 33 MHz PCI with five 120-pins
expansion-connectors. The second expansion-bus is 8.33 MHz EISA with three 198-pins expansion-connectors.
None slot is shared.
