RE: MCODE: Card_Reader 1G ROM
I can't believe its not GOT butter!
Is there really no commented source code for the Card Reader from HP ??? Angel, those spaces don't look like tables to me. To start with they only represent half the codes for the 67, also the codes that do fit are in higgledy-piggledy order - any responsible assembly table maker would have reduced the table order to 1,2,3,4... order. Next there doesn't seem to be any table addressing code in the whole of the card reader ROM, not even an offset address, by one or two bytes, i.e table 1 is at E469 so the search would be to look for an ld@ code having 9h as the last digit of a 4 digit address, but with an offset of a byte it would be 8h or if 16 bit offset it would be 7h, but none of these are apparent in the ROM. Its the same for the other table 2 at E5A7. Its like the 1G updated version has some left over code that is not cleaned up from the previous version. Just a few thoughts on the matter. DA |
