what machine and/or controller was this that had no ROM at all? I
never have dealt with any system that at least didn't have some type
of startup code somewhere other than a disk drive. DMA would need to
be setup unless it was hardwired. The original Intel Intellec-8
required that you enter a program jump into memory that pointed to
the program monitor. Intel didn't call it a BIOS though.
Hi
My understanding was that the first ones had no ROM
and used a DMA controller that loaded bootstrapping
code from the first sector on reset. I have such a
controller on my machine. All RAM, no ROMs.
