Couple of questions re CyberStormPPC cards: What exactly does 'ppcdiss.library' do?
I am not sure but I guess it allows to disassemble PPC code.
- and can the CSPPC's BIOS be safely 'downflashed' to an earlier version?
Yes, the flash program will replace the firmware and reset all settings independent of the version.
Note that if you have a flash version which is required to run a G-Rex or CVisionPPC, those extensions might not work any more if you downgrade to an earlier version.
