So how can I increase the size of the translation cache. I read from Transmeta's whitepaper that both BIOS and OS can do this. This mean that I should be able to insert a little piece of code in the kernel somewhere and experiment with the new setting. I guess it might be a PCI register? How about the persistent translation service on Linux? a) Transmeta will write it for us. b) Transmeta will open enough info. for us to write it our own.
