Hi Pavery,
I managed to get BIOS dump, and burned it into chip. It is newer version then my was, but it did work
This one is version 004C and it is probably dumped by some ROM reader.
Anyway, I played little bit with DEBUG after that. Both commands are here:
C:\> DEBUG
-N MYF000.BIN (resulting file will be named MYF000.BIN)
-R BX (set BX=0000H/CX=8000H as count of bytes to write, 00008000H = 32K)
BX 0000
:0000
-R CX
CX 0000
:8000
-M F000:0 8000 0100 (copy 32K bytes from F000:0 to offset 0100 in local segment)
-W 0100 (write from offset 0100 in local segment)
Writing 8000 bytes
-Q
C:\> DEBUG
-N MYF800.BIN (resulting file will be named MYF000.BIN)
-R BX (set BX=0000H/CX=8000H as count of bytes to write, 00008000H = 32K)
BX 0000
:0000
-R CX
CX 0000
:8000
-M F800:0 FFFF 0100 (copy 32K bytes from F800:0 to offset 0100 in local segment)
-W 0100 (write from offset 0100 in local segment)
Writing 8000 bytes
-Q
My T2100 has only one BIOS ROM. And content of BIOS rom is identical with export of second command (F800 - FFFF).
I guess that first command is for other rom chip which I don't have. Also not sure what it would be...maybe some testing tools, etc.
If you have time, you can try execute both commands and see how it looks like. Would be also good if you can open your computer and see which BIOS version do you have. It is on the sticker on top of BIOS chip.
Cheers,
Branko
