While listening to Meng-Shi Lim Pete heard:New Modem...

G'day Meng-Shi

 JP> Can you name a person who has?

 BG> Yep, everybody who cooked their AMD flash-ROM chips when
 BG> attempting to apply the 04/29 US/Canada SDL, that's who.  Mine
 BG> survived unscathed, but poor old Russell Brooks lost three of
 BG> his five Couriers in one fell swoop.

 ML> Sh*t! I didn't know FlashROM can be that dangerous. I guess it
 ML> is one of the very few cases where software can fry the
 ML> hardware. I'd better be careful with my PC Card modem upgrades.

I think your getting the wrong idea about the USR Flash-ROM problem,
The problem was caused by a dud batch of AMD flash chips that had
sections of their address space marked as read-only when it was
suppose to be read/write, when the bigger 04/29 code was loaded in it
attempted to write itself to a read only area causing an error which
stuffed the modem. BTW USR's are suppose to have a hardcoded
bootstrap loader thats invoked by setting the dip switches in a
sequence to allow you to reload earlier code, This apparently didn't
work either. All this is just info i've picked up reading the
USR_ECHO haven't had any problems myself.

 ML> BTW, can adjusting an S register permanently stuff up a modem?

Can't really say, You'd think a hard reset would restore everything.

     Pete.
