So, I hope I've made the correct calculations, I write them here for future reference:
SMA_SIZE values for different video ram sizes:
10000000b -> 0x80h (2MB/4MB) 10010000b -> 090xh (4MB/8MB) 10100000b -> 0A0xh (8MB/16MB) 10110000b -> 0B0xh (16MB/32MB) 11000000b -> 0C0xh (32MB/64MB) 11010000b -> 0D0xh (64MB/na)
What I don't understand now is the "double" size value (with the 'not supported' value for 0xD0). What does it mean?
You don't have to care about the double size stuff. Some time in the history, there is a feature to add DRAM card for internal VGA. It did not work out.
Interesting. But, I was asking to myself... how much time does the hard-disk need to spin-up? I've made few tests and it seems quite fast, only few seconds. How much time is it possible to gain with a CF ide device? I have a small CF card, I should buy the CF-IDE adapter, but I have no idea of the advantages it would bring to me.
For CF/DOM, it is "INSTANT'.
