We E55 users have to work and fight very hard !!! We cannot accept to read a sentence like `not supported' !!! Ok, let us come to the facts. The E55 is a nice server, but it includes many proprietary parts. These are the I/O bus system, and the following devices: MUX 8/16-way serial interface (also affected is the serial console) Parallel port (not so important in the first run) Complete SCSI system The CPU (core systemw with RAM/Cache) and the ethernet is working well and quite with a good performace. It was very important for me to boot this machine. The image booting via ethernet (BOOTP/TFTP) works very well. The first step was to get an running console (serial). For this I started with a hack, using the ROM PDC console via a polling driver, and so I could start the machine June 2001. End of 2001 I rewrote this driver as clean one, and Ryan added the config stuff. So you can use the default linux PA-RISC kernel to boot the E55 as "diskless server" via NFS-ROOT and a serial ROM console. What to do: ----------- Checkout a kernel, and enable the PDC ROM console in the "Character Devices" under the "Non-standard serial support". Further follow the instructions for this driver (Creating a /dev/ttyB0, and use this device as login device). With this driver we have a chance to do further development on the device driver programming. I am waiting on documentation to help developing drivers, but I have to wait. HELLO ot the others. What is the status on the docu or drivers ? Good luck in starting up the E55 (it is quite straignt and no real hacks or patches are needed !). Christoph P.
