Of course there are SCSI drivers and third party drivers, but I'm really just interested in SATA.
There is one third-party driver for Promise SATA 150/300 PCI controllers:Aminet-ulsata2
I tested last week one, and speed increase is remarkable, compared to Sil SATA 150 controllers.
( I will post some results in near future).
Unfortunatelly, you cannot boot MorphOS directly from drive on Promise controller, and AmigaOS have no drivers at all. It makes this controller nearly unusable on my Pegasos with MorphOS and AmigaOS. ( only for Work: atd.)
It will be great to have this controller in supported hardware.
Pegasos II 1.33GHz, AmigaOne X1000, Powermac G5 Quad, iMac G5, Powerbook G4 and Z10PE-D16 WS
MorphOS, AmigaOS, Debian, Ubuntu, OSX, NetBSD, Win7
