Shalom Eri, >From what I understand, Promise will only support 2.4.18 and only Red Hat Linux. And from the emails I saw they will never be resources to be compatible with Linux because they refuse the "open source" system. Personally I would have thought that their RAID technology would be mainly hardware and so releasing the driving software would not show any patented technology but it does not sound that way. Anyway, if you wish to stay RH7.3 and 2.4.18 forever (or until Promise change their views) then you can use their released driver otherwise I would suggest that you try to make this works on the kernel so you can move on with the linux future kernels. As for yuor software, I would think that the Kernel released won't affect them except maybe if they reference specific kernel function but I would imagine that the Linux group try their upmost to be backward compatible...
