Can someone help me out I want to reprograme the original bios with the following:-

EvoX and the original bios.

Now they are a full 1M files and I need to split them into 1/4's.

Can I do this with winhex?

What part of the original bios file do I use, what part of Evox do I use?

Then what I'll do is have a switch on the relevant address line to pull it high or low depending on what part of the file it runs.

if its in 1/4's then you could use two switches and run 4 bios files....in that case has anybody got the relevant 256k files for:-

Xtender1.1
Xtender1.3
EvoX
&
the original bios

I want to keep a original bios just in case online gaming in the future can detect the bios settings.

Just one more thing what solder points on the enigmah/xtender disable macrovision.

Thanks for any help
