Onboard SCSI
Onboard SCSI is provided with an Adaptec AIC-7892 SCSI controller chip,
which supports single channel, Ultra160 SCSI at a burst throughput rate of
160 MB/sec. The P3TDDR provides two SCSI ports.
PCI Expansion Slots
The P3TDDR has three 32-bit 33 MHz PCI slots. However, the 6011D has
only one 64/32-bit 33 MHz PCI slot available, since a riser card is used in
PCI#1 slot to allow a full height PCI card to be used in a 1U chassis (such
PCI cards are too long to fit within the chassis when the riser card is used
in the PCI#2 slot).
ATI Graphics Controller
The P3TDDR has an integrated ATI video controller based on the Rage XL
graphics chip. The Rage XL fully supports sideband addressing. An 8 MB
graphics memory chip has been integrated onboard the P3TDDR to provide
graphics memory. This onboard graphics package provides a bandwidth of
up to 512 MB/sec over a 32-bit graphics memory bus.
Onboard Controllers/Ports
One floppy drive controller and two onboard IDE controllers support up to
four hard drives or ATAPI devices.
port, four USB ports, PS/2 mouse and keyboard ports, a video (monitor)
port, one parallel port and two 10/100 MB Intel 82559 Ethernet (NIC) ports,
which back each other up in case one port loses its connection.
P3TDDR also has an onboard ATI graphics controller (see above).
Other Features
Other onboard features that promote system health include five voltage
monitors, two CPU temperature sensors, four fan speed sensors, a chas-
sis intrusion header, auto-switching voltage regulators, chassis and CPU
overheat sensors, virus protection and BIOS rescue. Watchdog circuitry is
also provided and requires scripting for implementation.
Onboard I/O ports include one COM
