Don Hooper <hoop@khonshu.Colorado.EDU> came up with the right answer. He stated
] The solution is to fix the eeprom to know exactly
] the kind of monitor/framebuffer you are using (see eeprom(8)). In our
] case, we added GX boards to some machines, and reset did this same thing
] to us until we change a couple of eeprom locations to tell it about the
] new framebuffer situation.
This was the case I was faced with. The fix I put in place was provided by
Mr. Hooper.
] Here are the two
] eeprom tweaks I've used to fix this problem; I forget which is which, so if one
] of them prompts you with the value you would be setting, you can just enter a
] SPACE, and then a RETURN:
] q16
] xy? 13
] q1F
] zq? 20
] Where xy and zq are the hex values already in those locations as the
monitor reports
] to you before asking for possible replacement values.
In my case 1F had to be changed from 12 to 20. eeprom -i reflects the change as
"console=b&w" even though it is color! "reset" does not cause a crash anymore.
Thanks to all that gave assistance. Most of whom suggested ROM revision upgrades.
This may be another avenue to consider. ( But, it's working now! )
