Monitor "Blinking" on and off during 6.1 install on Ultra 60

[Andrew Belashov]

Hello, Patrick!

For the record.
On Sun hardware display resolution determined at boot up
by the manner in which sense lines (ID Bits) are terminated
within the local monitor. See 13W3 Sun Color Video Standard.

You may change the autodetect setting at the OpenBoot ok prompt.
For example:
ok setenv output-device screen:r1280x1024x76
ok reset
