forget post codes under linux. port 80 is used for io delays there.
no kidding.
and I was looking for some ready-to-use delay loop to hold stuff after using port 80.
either way ended up using serial port
actually, is linux actually writing to those ports?
I have been here looking over an LK book and it mentions that the delay is being done by _reading_ only those ports, not writing.
It also mentions that jumps were used before. It would be worthwhile to re-examine the delays used in IDE driver in ADLO code. And change it to perhaps reading the port 0x80. It could potentially make it more reliable.
