Re: Re: odd vectors on SD

Well it actually gave me 2 eeprom errors and since
they were all new flashes, I replaced the sockets and
now its totally dead..arrrgghh...

I get some odd beeps now.. I goes like:

-1 low tone but very short.
-pause of about 1-2 seconds
-2 low tones and 2 high tones which in itself should
signify bad ram at E1. I replaced that, and get the
exact same set of tones..so I replaced H1 as well and
still get the same sequence of tones..including that
oddball very short low tone.

In regular gameplay mode it is watchdog resetting.
