[comp.sys.amiga] A501 clock problems

finkel@TAURUS.BITNET (02/28/89)

Well, my A501's clock module decided to go berzerk again!

It was caused by a memory diagnostic program that went loose.

I can't set my clock any more! setclock responds with:
Battery clock not found.

This is not the first time it happened to me. last time, I solved it
by disconnecting the battery and reconnecting it. I don't want to
repeat this. I checked some of the advises I got last time , and:

1) The 1.2 setclock DOES NOT WORK. not the 'save' neither the 'load'.
2) I got a program called 'chronos' ( by Dave Thomas ), that is supposed to
   cure the problem. it first writes 0xf1 to 0xdc0000+61, ( the comment says tha
this sets the 'reset' bit ). it then writes 0xf4 to the same address ( 0xdc0000+
   this program DOES NOT WORK!

any help? a better explanation of the OKI 6264 chip's registers ( the clock chip
send me EMail!

This is not the first time my clock goes wild, and I'm afraid not the last one.
I must find a way to reset it without disconnecting the battery!!!

To Andy Finkel ( If you happen to read this) :
Last time my clock crashed, you posted an article mentioning the missing
'reset' option in the 1.3 setclock. can you please post a simple routine to
reset the clock???
