Actually, a number of the late model 800 series machines
look a lot like the late model 700 series machines.. The known
exceptions are the V-class, and perhaps the SuperDome.

- Quite true. I have a ancient (5yr old) 9000/F10, which is
- unfortunately an 817 (IIRC) CPU. While I would keep 10.20 on it as a
- secondary boot, I too would love to get NetBSD on it. However, near
- as I can tell, HP has yet to release the information on the bus and
- from what I hear probably has no intention to do so due to the immense
- amounts of propritary and NDA information in what internal docs they
- can still find. From what I can tell, here are the critical docs we
- are still missing (at least as of a few months ago) for just the
- simple F10:
- - CPU bus
- - Backplane bus
- - I/O module (which includes the console, SCSI and ethernet)
Yup.. The basic backplane information on many of the
older server class (800 series) systems is non-existant (even
within HP, it seems) or unreleasable..
- The one thing I do have information on is their boot loader format,
- for which I had written a program which understood about 80% of the
- information on my HD and 10.20 install CD-ROM. However, when I
- started working at my current employer (a large firm recently in the
- news), I stopped working on this lest it get tagged as IP.
Would you care to share the program sources?? And the
information sources used to write the program?? (I suspect I
already have them, or pointers, but it doesn't hurt to have more
I really need to spend some time on the hppa port! (I
don't know how Jason gets so much done! Work, Life, and I run
out before NetBSD gets its slice!)
