cg> How long does your CF take to boot ETH-Oberon ?
The Toshiba T2100, 80486, starts from the CF in 23 s.
The Toshiba 205CDS, 100 MHz Pentium, starts from the hdd in 30 s.
I've added this to http://carnot.yi.org/ExampleSystems.html .
Thanks for the suggestion.
I've never done any low level programming. Perhaps someone
can help with decoding the Init string for VGA, "b81200cd10".
Referring the to the One-Byte Opcode Map on page A-4 of
the Intel 386 Programmer's Reference Manual, B8 is MOV eAX.
What is eAX?
Referring to MOV on page 17-114,
"B8+ rw MOV reg16, imm16 2 [clocks], Move immediate word to register".
So "b81200" means "put 00 into register 12"?
Thanks, ... Peter E.
