Hi.

Good news: I got a kernel booting diskless to single user mode with the
old userland fron the last snapshoot. I commented out the third
instruction of cpu_switch() in locore.s that writes NULL to curlwp. The
kernel allways crashed at that point. I will try to investigate this
later.
ENTRY(cpu_switch,128)

        /*
         * Clear curlwp so that we don't accumulate system time while
idle.
         */
        ldil    L%curlwp, %t1
        ldw     R%curlwp(%t1), %arg2
/*      stw     %r0, R%curlwp(%t1) */
        /* remain on the old (curlwp)'s stack until we have a better
choice */


Only the 715/100XC has a disk. Due to the recent changes to the hp700
disklabel(5) code I have no working disklabel(8). I need to build a
-current userland, this will take some time. So diskless is all at the
moment.

On the dmesg(8) output below you can see that this stuff runs on three
mayor machine types: B132L with the newer device scanning code and
Phantom port, 715/100XC with the old device scanning code and LASI and
on a 715/33 with old device scanning code and ASP chip set. 

If you have a [ABCJK] class machine and you want to help: I will put
this test kernel and source diffs on
http://www.unixag-kl.fh-kl.de/~jkunz/NetBSD/hp700/ later tonight. The
old userland is still available on the NetBSD ftp site.
(ftp://ftp.NetBSD.org/pub/NetBSD/arch/hp700/snapshot/20020706-1.6D/ and
ftp://ftp.NetBSD.org/pub/NetBSD/misc/fredette/hp700/hp700-update-20020905.tar.gz)
Please give it a test. Especially of interrest are the machine types:
C100/C110, A180 and J2xx. They have only slightly different hardware
then my B132L so they may just run.
