"hdx=nodma" : disallow DMA
"idebus=xx" : inform IDE driver of VESA/PCI bus speed in MHz,
where "xx" is between 20 and 66 inclusive,
used when tuning chipset PIO modes.
For PCI bus, 25 is correct for a P75 system,
30 is correct for P90,P120,P180 systems,
and 33 is used for P100,P133,P166 systems.
If in doubt, use idebus=33 for PCI.
As for VLB, it is safest to not specify it.
Bigger values are safer than smaller ones.
