HP Visualize B132L, B160L & B180L
4.17 HP Visualize B132L, B160L & B180L
4.17.1 Overview
These are very nice, small entry-level workstations. Still based on a 32-bit PA-RISC CPU they were de-
signed as successors to the successful 715 workstations with better performance and I/O-expandability.
They were developed alongside the C-Class workstations, sharing a similar casing concept but integrat-
ing more functionality onto on single mainboard to save manufacturing costs. The +-models (B132L+,
B180L+) differ from the others in having Ultra-Wide SE SCSI and 10/100Mb Ethernet rather than
Fast-Wide HVD SCSI and only 10Mb Ethernet.
Several B132L and B160L models feature a faulty PCI backplane chip (Dino), which could result in data
loss. A firmware patch in PDC version 6.1 added a check for the faulty chip if such a chip is found,
subsequent PCI cards in the PCI slots in question are disabled and the system halts a boot-up/PDC.
Model numbers: all have the HP 9000/778 model number.
4.17.2 Internals
CPU
B132L: PA-7300LC 132MHz with 64/64KB int. L1 (+ 1MB ext. L2)
B132L+: PA-7300LC 132MHz with 64/64KB int. L1 (+ 1MB ext. L2)
B160L: PA-7300LC 160MHz with 64/64KB int. L1 (+ 1MB ext. L2)
B180L+: PA-7300LC 180MHz with 64/64KB int. L1 (+ 1MB ext. L2)
The external L2 cache SRAM is optional and is installed in two DIMM slots below the CPU socket.
The modules must be of equal size. Usually, these systems come with 2 512KB modules, totalling in
1MB L2.
