NetBSD ported to Sun JavaStation Espresso
Julian Coleman wrote to the port-sparc mailing list that
``[w]ith help from uwe@, port-sparc now boots single user on the JavaStation
Espresso. Minor modifications were needed to the PCI and interrupt mapping
code, as the Espresso is very similar to the (already supported) Krups.''
See
Julian's mail
for more information including a dmesg output.
More information on the hardware is available
in the Linux on the Sun JavaStation NC HOWTO,
which tells us that an Espresso is
``extremely rare to find. It was never available for sale in quantities to either the general public or the initial JavaStation deployments, limiting the model's production quantity. To call this "Generation Three" of the JavaStation may be improper, as Espresso is nothing like the generation three JavaStation written about in early Sun marketing literature.
The Espresso was designed as an extension of the Krups. It was geared to sites that wanted a little bit more functionality and expansion capability from their JavaStations: a cross between an NC and a workstation.
Espresso is powered by the same 110Mhz MicroSPARC IIep chip as Krups . It's mainboard is similar to Krups, with the addition of PCI slots and an IDE channel for local hard disks. The IDE on Espresso was not enabled in the demo units. Those who have tried to make it work have concluded the wiring is incorrect, and it requires a hardware rework to get going.
Espresso continues with the PS2 keyboard and PS2 mouse ports from Mr. Coffee and Krups.
Espresso uses the same 168-pin, 3.3V unbuffered EDO DIMMs as Krups. The maximum amount of memory for Espresso is reported to be 96MB. As with the Mr. Coffee and Krups , the number "xx" in the Sun option number refers to the amount of memory shipped with the unit.
For video display, the Espresso uses the PCI-based IGS C2000 framebuffer, along with the same standard VGA port connector as Krups and Mr. Coffee. The on-board audio remains a Crystal CS4231 chip like Krups, and the network interface remains a Sun HappyMeal 10/100 Mbps interface like Krups as well.
Espresso came with the 9-pin serial port and 1/8" audio out and 1/8" audio in jacks of Krups, and a new addition of a parallel port, and a second 9-pin serial port. Espresso also comes with the flash memory to load your OS on and bypass the network boot cycle.
One new addition to the Espresso is a smart card slot. ''
