I've successfully booted both my HP 9000/380 and 425e systems from a
Toshiba SD-M1711 DVD-ROM drive jumpered to 512 byte/sector mode.
In my case I was using CD images provided by David Collins from
hpmuseum.net. The boot CD image that I got from him has the same md5sum
as the hpux9_install.iso image that I just downloaded from bitsavers. I
didn't need to do anything special to burn it or boot from it. It just
worked.

Couple of related things, does anyone have a list of
SCSI CDROMs known to boot on the 68K 9000s?
I've ordered another A1999 to see if my drive is just bad, and have started digging
through my
boxes of drives for other models to test.
