Hi, >First, the second flash is mapped at 0x1.a000.0000, not at 0x1.e000.0000 >as I posted in my first mail.
Actually, I am impressed that you found this information at all. I've searched through the programming manual and found nothing about it. [del] >Looking at the 2 prom regions, 1 seems to be empty (the one at >0x1.8000.0000) and contains data (the one at 0x1.a000.0000). Can someone >with a working DEC 3000 verify this ?

Does a DEPOSIT command care what type of target it has? I mean, I'm surely not a hardware guy (being at home in UNIX userspace for ugh... 20 years, I am certainly not), but writing in a flash EPROM is a bit different than writing in a DRAM, right?
