you might actually want to LOOK at the link i gave about the update. it answers most of your questions.
Yes, I did look at the links, I clicked the link on the left frame for the English version before the 1st screen came up on the right, that had the CPU info, I didn't expect that I had to read the first page when I saw the English link. Now I saw it.
No, CPU's are not sodered in. This is a hardware update. You need a piece of wire and a k6/2-500 2.2v. THe only difference between a raq3 and raq4 is the OS and 150mhz. I updated the OS and added 200mhz.
So to do this upgrade, do I need to upgrade the OS or can I just do the speed thing and leave everything else the same. I'm not sure if I followed correctly on this point.
any OTHER problems? I didn't have one problem, let alone OTHER problems.
that is good to know!! Thanks, Jale
