Setting the manufacture's jdec ID so evox recognizes it has nothing to do with banking a tsop or the 3 wire trick to allow access to hidden banks. What you want to do is a 3 wire trick on the doux tsop, not the xbox tsop.
The address bus width is 32 bits. Thats 8 clock cycles of address info for 3 data cycles of real bios info. So if you ever see a 3 wire tutorial for tsop restoration it's based on manipulating the 18th, 19th and 20th bit of the 32 address bits. Bits can either have +5v and be considered 1 or be at ground and be considered a 0. The bits can change 33 million times a second and you need a CPLD to change them on the fly that fast. Some bits are more static, and you can 3 wire those.
Now the actual bits 18, 19 and 20 correspond to actual pins on the tsop meaning legs of the tsop are known as A-18, A-19 and A-20 and any pin diagram of a tsop shows the legs for those bit lines.
Doux already has a switch set up on A-19 or whatever. When you switch that leg of the tsop to 5v or 0 volts via the switch you manipulating the address mapping. If you put a switch on the next pin lower you could boot into the lower bank IF YOU FLASHED it with a VALID 256k bios and it stopped flashing 1/2 way.
** Before you do this you need to disconnect that pin from how the LPC bus that drives it ****
What would take me 3 mins to fix you'd probably work on for 3 days and end up screwing over so maybe stick with a hotswap method with another chip since you are obviously a noob.
why are you so quick to jump on people? i am deffinatly not a noob. ive been with the scene for quite sometime (not only here but other places as well). This is only the first time that i have had a bad flash.
at anyrate, i did flash a good and working (i know because ive used it many times before) 256k Evox M8 plus 16 bios to the chip and now it frags. I was able to to get to the evox flashing menu but when i tired to flash it with the m8 512k bios, it says invalid size. if i attempt to flash it with the 256k bios, it flashes but still presents the same problem as before.
thanks for your help, please dont assume that because i have a problem with one thing, that im a newb. everybody can get hung up somewhere, just because it happens doesnt mean your retarded and dont know jack shit.
dont get me wrong, your help is appreciated, but i hate it when people think that other people have no idea what they are talking about
