yes, you right, pinczakko made a great investigation in this area!
what i ment about hardware were exactly a thing where insert this rom with rom extension and a tool to write it (if you use not electrically erased eprom) 
to play with this i made 2 boards: one universal 2716-27512 and another for 27256, and two eprom programmers, as i have a lot of used UV eproms when i'll have some time i hope to continue this game :unsure: would be nice to be not alone 
most of this i have been discussing there: http://board.flatassembler.net/topic.php?t=9181 also you may look at the pictures (as i have no translated to english version  ) at some of my stuff there:

In similar fashion the signature and check sum will be checked. Finally the entry point will be far jumped. i see, it's slightly different then i have planning to do - i had wish to use old motherboard as diskless system. mikegonta wrote: I stand corrected. It's not ISA vs PCI, but rather the Plug and Play extensions. i see, you're right about netcard as easiest platform to hold rom extension, i did not know about such troubles with int 19h hooking as I have not been interesting with PCI bus yet, because my targets are exactly old motherboards without PCI bus on them. it's a subject to test... regards! _________________ UNICODE forever! |
