                      9: On most models, you can configure the Boot ROM to use a serial console
                     10: instead of a locally attached keyboard and the framebuffer. The serial
                     11: console will typically run at 9600 bps, 8 N 1 on Port "A" or "1". The
                     12: procedure varies between models, but you *will* need a keyboard and

                     16: There are some tricks you can play to force a serial console without
                     17: initially connecting a keyboard and monitor. For models with removable
                     18: framebuffers (such as the 720, 730, 735, and 755), simply remove the SGC
                     19: framebuffer and the system will default to serial console. Apparently,

                     95: 
                     96: The hp700 port of NetBSD was started by Matt Fredette in October 2001. He started working with Michael Shalayeff's [OpenBSD/hppa](http://www.openbsd.org/hppa.html) sources at that time, and after much work had it booting multiuser in March of 2002. At that time he began merging the port into the NetBSD tree.
                     97: 
                     98: The port was renamed NetBSD/hppa for the 7.0 release.
