Hi All,

      My beige G3 (OF 2.4) works once again! As Chris and Bill mentioned,
the step I missed was unplugging the power cable. After unplugging the
power cable connecting the power supply to the motherboard, and then
removing the battery for 10 hours, my machine was restored. I think i could
have left the battery unplugged for less time, but I wanted to ensure that
the machine's OF settings were well and truely reset (:

      Thanks to everyone who came to assisting a mac-newbie.

Humbly Yours,

As others have said, removing the battery works. Though 1) disconnect
power, and 2) do it longer. Also, you can try shorting the battery
contacts with say a screwdriver (if you have a 1k resistor or so, that'd
be better; I used a screwdriver and my Beige G3 266 was fine). The RTC
draws little power, and internal capacitance keeps it alive for a while.
:-)

Oh, I learned this after doing setenv real-base f0000000 (note extra 2
'00's).

Take care,

Bill
