It is already deep inside my desktop system -- I can't reach there...
The "marketing name" is SATA300 TX2plus (one PATA and 2 SATA channels),
although TX4 can't be very different (it has 4 SATA channels instead of 2):
After applying the patch, it is identified as:
atapci1: <Promise PDC20775 SATA150 controller> port
0xc000-0xc07f,0xc400-0xc4ff mem 0xf7051000-0xf7051fff,0xf7000000-0xf701ffff
irq 9 at device 11.0 on pci0
`pciconv -lv' says:
atapci1@pci0:11:0: class=0x018000 card=0x3d73105a chip=0x3d73105a
rev=0x02 hdr=0x00
vendor = 'Promise Technology Inc'
class = mass storage
IMHO, the driver should be smarter in identifying devices, you have not seen
before as compatible with something, you have. Anything unknown, with Promise
being the vendor and 'mass storate' being the class should be examined as an
ATA controller, for example.
You can be very conservative enabling features, and even print a ton of
warnings, but it should be possible to install/boot FreeBSD with such
hardware. Is this not doable?
