next in thread | raw e-mail | index | archive | help
Hello, I'm writing a device driver which needs to do some floating point calculations, but when the floating point code executes the kernel traps with number 22 "FPU device not available". I'm have an AMD 486DX4-120. I'm not concerned with portability at this time (ie running on SX's). Would someone care to explain what's going on? Thanks. Alex Jones
