Binhack - What changes does it make?

[darklegion]

Just wondering what binhack does so I can modify the files manually without having to use binhack (I use linux).I am pretty sure that as far as the bootfiles go it just changes the lba to the msinfo value,but are there any changes to the ip.bin? I would think that there would be since it asks for an ip.bin,but what are these changes exactly? Also I am just wondering what certain booting problems indicate such as:
1.Constanly resetting dc after sega logo
2.Jump back to dashboard
3.Wierd laser noises

Knowing what these mean could help figure out where mistakes are being made

Oh and 1 more question,I have come to assume that isofix does not do any binhacking it just pads the data up to the same lba that it originally used when it was originally in audio/data form....is this correct?

Thanks
