Subject: [PATCH] ide: skip probing port if "hdx=noprobe" was used for both
devices on it
* Skip probing port if "hdx=noprobe" parameter was used for both devices on it.
* Obsolete "idex=noprobe" parameter - it only works for ide_generic, cmd640
and PCI hosts in Compatibility mode (on alpha/x86/ia64/m32r/mips/ppc32).

As for VLB, it is safest to not specify it.
Bigger values are safer than smaller ones.

where "base" is usually 0x1f0 or 0x170
