the scratch RAM for data normally found in the SEEPROM (presumably in the event that the SEEPROM is unavailable or can't be read). This code causes a spontaneous reboot on monster.osd.bsdi.com, which has an embedded aic7880 controller. The problem appears to happen either when it writes to the SCBPTR port and then reads from the SCB_CONTROL port. Somewhere during the inb/outb operations, the system has a heart attack and restarts. This code looks very suspicious, particularly since it has unconditionalized debug mesages such as "Got here!" and "And it even worked!". With this block #ifdef'ed out, the machine boots and runs properly. I stronly suggest that it stay #ifdef'ed out until it's properly tested.
