I'm currently busy disassembling the ET4000 rev 8.01 BIOS for figuring out the RAMDAC detection algorithm (for making the RAMDAC detection of emulated RAMDACs(e.g. UniPCemu, Dosbox etc.) more accurate in being detected).
Can such a disassembly file be uploaded on vogons, under the Fair Use (If I'm reading the ters of use correct) uploading rule? I don't know if it's allowed or not due to copyright etc. (if it's still copyrighted or not, which I doubt for the most part)? I so far have most interesting parts disassembled (almost the entire detection algorithm, except 1 or 2 subfunctions), which would add a lot of (unclear in the WhatVGA specs) clearing up of information regarding detecting said RAMDACs. This would be especially interesting to emulator builders like myself. And of course fans of retro hardware (in particular people dealing with things like said RAMDAC).
I'm currently doing the disassembly and informational part using the IDA disassembler, adding documentation by creating the required functions from the code and renaming them to be describing what they do. Left most of the ROM alone, just focussing on figuring out the entry points, then getting down to the RAMDAC detection part and creating functions and informational descriptions of the blocks within it (to create a full description of how the RAMDACs are actually detected).
Although the IDA reverse engineering file seems to contain the entire ROM and might be able to reassemble the ROM (don't know for sure, due to assembler ambiguations. Although the hex view clearly shows the original ROM), which might be copyrighted?
