Does Haiku support SATA II disks ?
I have booted it on both my Acer W500 and ASUS 1215b an for both devices the hard drives aren't recognised.
For both I've submitted full bug reports.
As I know SATA II is supported, maybe you have some other chipset, what is not supported by Haiku. My previous PC had a SATA II Samsung HDD, and I had Haiku installed on it.
Unfortunatelly, on my new PC I have Kingston mSATA SSD, but Haiku cannot find it (I have Intel DH61AG board).
