from all of the things i have done as in hacking the 1394.inf to show the older driver , suprisingly it was already there ,, windows XP already has the drivers . everyting is there , the only problem is getting it to use "ohci1394.sys" instead of sony1394, but even though that 1394.inf says "sony1394.sys" noware in the device driver it still asks for it , heck i even tryed renaming the ohci1394.sys .. and it almost worked , well it got past the main will not work , i got a can not Start Device error after that ,, you think that with how tecnicly advanced Japan is that someone in japan would be having the same problem and have the drivers for it... but thats the trouble with legacey Computers , so old no one thinks people will be using them with newer operating systems ..
On a side note .. i have a PCG-Z505rx (most all the older PII have the same 1394 card in them)
If anyone manages to hack the driver and it works correctly with the outdated verson of sony1394.sys or ohci1394.sys i like a copy of it.
