* Uwe Hermann <uwe at hermann-uwe.de> [070528 02:40]:
> Lower the RAM init delays we use on the Intel 440BX.
> 
> As per JEDEC, we should wait 200us until voltages and clocks are stable.
> Then apply NOPs for 200 clock cycles (for simplicity we use 200us here).
> 
> All other delays are so low that we get away with just waiting 1us.
