IMHO this is true WITH RESTRICTIONS, because the ACK - compiler uses 16bit the maximum size of an array is 64k. If you want more cache buffers than 62 (one cache buffer is bigger than 1k because it's hold in a struct with some other information about the buffer status). Anytime I try to boot a kernel with NR_CACHE_BUFS > 62 it hangs in the startup, on an ST (running Minix 1.5.10.3) this means that the screen will remain white. The solution to this can be to use a 32 bit integer compiler (I intend to try this but I'm not very sure this can be done without any modifications to the sources) QUESTION: Did anybode write some routines for the lib68k to make 'printf()' able to print float's ? As far as I know at least two (assembly) routines have to be rewritten, I tried to do it last weekend, but my knowledge of floating point was to minimal to handle this.
