Are you talking about a BIOS ? I think you're well beyond the subject...
T. To be perfectly honest, BIOS is really a bit of an extra layer of stuff that not many people, (not even programmers), want.
Yes I have gone beyond the subject, but what I wish to create is an 'OS on a chip'. Unfortunately for you guys, you get all my spam, since the OpenBIOS are the only people who can support me on this venture.
My proposition is to take a whopping great EPROM chip, + a whacking small OS Microkernel, ( < 64 Kb ), and bundle them together in one single machine.
Here is an outline of my proposed architectural idea:
+-----------+ +------------+ +------------+ | | | | | | | Coldfire | | "" | | "" | | CPU | | "" | | "" | etc -> | | | | | | +-----------+ +------------+ +------------+ | | | | | | ---| |------------| |------------| |------ Shared Bus Topology ---| |------------| |------------| |------ | | | | | | +--- ---+ +---- -----+ +---- -----+ | | | Flash | | 64K | | I/O PIC | | HDD | | EEPROM | | | +------------+ +------------+ +--| |--+ | |
The Flash HDD is available from Bimicro Networks at:

64K EEPROMs can be obtained from motorola, as can PICs DDR RAM etc.
That is about as far as the idea goes at present.
All the best, Gavin.
