I understand now. I don't see any point in asking Askey - I've heard

to many lies from them.

I guess EEPROM equivalent to 27C4096 wouldn't cost a fortune and

when USR releases v42bis fix I'm willing to test if it works on my

modem. If it doesn't flash then I guess I'll need EPROM programmer

and do it hard way.



BTW, what's required for flashing support? There aren't many

components around ROM/RAM area apart from a couple of 245 and a one

transistor (and few passive components of course). Bloody hard to

trace the tracks on this board, I suppose my eyes can remember

better times.
