Modules designed for 5.0V signaling and 33-MHz bus speed can only operate in
5.0V/33-MHz slots (slots 5 and 6).
A maximum of two 5V modules can be installed in the system.
Modules designed for 3.3 V signaling and 66-MHz bus speed can only operate in
66-MHz slots (slots 1, 2, 3, 4).
Universal PCI modules can operate in all slots (3.3V and 5.0V).
Universal PCI modules can operate at a maximum bus speed of 33 MHz or
66 MHz.
Universal PCI modules operating at 33 MHz placed in a 66-MHz slot will reduce the
entire hose to operate at 33 MHz.
Universal PCI modules capable of operating at 66 MHz when placed in a 33-MHz
slot will operate at 33 MHz.

PCI Module Descriptions :
PCI modules listed in this document as 33 MHz or 66 MHz refers to the module's maximum
PCI bus speed.
Modules that can only operate at 5V are designated as 5V – 33-MHz modules.
Universal PCI modules are designated as 3.3/5V and can be installed into 33-MHz
or 66-MHz slots.
The AlphaServer DS25 provides three PCI buses (hoses) that drive the six slots. A fourth
hose drives the on-board Gbit Ethernet and dual channel Ultra3 SCSI adapter.
Hose 0 – 33 MHz driving slots 5 and 6
Hose 3 – 66 MHz driving slots 3 and 4
Hose 1 – 66 MHz driving slots 1 and 2
