My first question: does this flash Rom having been optimised for BIOS and boot use, hinder in any way generating read addresses with a binary counter to access the full range sequentially?
Second question: What's the easiest route/minimalist approach to opening a short audio file in XP-Pro and writing it to said flash ROM?
No, you can address it like any other staic memory.
Whatever you intend to use to playback the audio should be made to program the memory as well. A microcontroller would seem to be the simplest choice.
====================================
I was hoping the bytes could somehow be made to emerge from the LPT1 port, presumably the address counter would have to have a little extra logic to set up the address and data then strobe the write enable/chip enable - shouldn't be too much more extra logic to hold the ready pin on the LPT port for the write time and address setup time of the next byte.

Failure does not prove something is impossible, failure simply
indicates you are not using the right tools...

That would be very difficult, if you dont allready have a device for playback there isn't much point programming the chip. You apear to be developing a rather down spected mp3 player.

Even what I'm after is probably a bit OTT for a novelty doorbell.
Ian and everyone, I've got a few NOS E28F400B5B80 devices you can have for the cost of postage. Just send me a stamped self-addressed anti-static package and I will get them to you. They're in 48-Lead TSOP; 512MB x 8 or 256KB x 16.

Thanks for the kind offer but I actually have more decommisioned old MOBOs with flash ROMs than I originally thought - there's probably even more still in cases that I CBA evicting untill I have better boards to take their place.
As yet its still only a "thinking about it" project with a fair bit of study still to do before I even put pen to paper.
As someone else pointed out such novelty doorbells are already in the shops (but probably not with the sound I want) so its just a one-off project to amuse myself.
