the former 2.4.x kernel found my IDE disk as CHS=2434/255/63 (LBA mode),
but the 2.6.x kernel saw it as CHS=16384/16/63,
as the parameters on the partition table is based on the LBA mode, different from the parameters reported by the kernel, so it confused, and complained too much, can hardly be used.
so how can I get back the LBA mode for IDE disk?
any advice is appreciated.
