The saga of the soekris box continues....

I decided to once again try pxe booting to see if I could get this
box to stay up for any length of time. The plan was to get it netbooted,
then install onto the microdrive from the netboot.

dhcp server and pxe server are both on the same netbsd 1.6.1 box.
Diskless tree is setup in /export/diskless/root.

I needed to cp /export/diskless/root/netbsd to
/export/diskless/root/pxeboot_ia32_com0.bin for some reason, the boot
wouldn't find (or couldn't open, despite my making various permissions
wide open just 'to see') /export/disklex/root/netbsd.

This may be something funky with my dhcp server setup...

Anyway.. the system panics during boot, and these are the messages I see :

This is very reproducible. I suspected the IBM microdrive in wd0, so
I removed that ad repeated.

The same thing happens, except this time panic occurs a few lines earlier at :

Any help greatly appreciated, I've had this box now for about four months
and I'd really like to get some use out of it :)

Cheers,
