First time i'am searching for P45-C51, and finaly it's directly P55.
Sonotone write P55-CD53 dsdt and says fully hackintosh compliant.
Tonymacx86 says it's in iboot + multibeast release; No more, it's mine
Raid13 from mac-on-pc.fr help me to make choice

finding nvidia GPU was very hard for newbie with name and specs
this test make me cry 9400 and 9500 GT out (site in french)
this one make scale between nvidia and ati
this other says 9600 GT are'nt VC-1 hard coded and so ? it's information :?
9600 GT cost nearly 9800 GT green => 9800 GT

For cpu
this site make 1156's cpu charts

for case box
this site (in french too) talk about silent solutions

priority is for first hack with good video and good silent box. CPU can wait, I5 750 is too hight for my bank. 2 HDD for simple multi-boot, video storage and clone partition area (testing hackintosh )

in few month, if this part work fine
i'am searching for
802.11N pci card compliant in 32/64bits mode
24" LCD IPS technology screen

On bios after load optimized bios
disable extra Raid/ide (stop jmicron scan during install)
disable motherboard logo
disable quick boot
enable AHCI

iboot (nvidia) don't work => -x -v no more
Iboot-supported + 10.6.3 don't work keyboard not present during installation process
Iboot-supported + 10.6.0 works without flags
Iboot-supported don't see my Seagate 500GO sata 7200.12 (disk utility scan loop without exit capacity)

On my Caviar 1To
Iboot-supported + 10.6.0 works => installation OK
after reboot with seagate 500Go online, disk utility see it and format OK. But if i restart installation process without Caviar green and only Seagate 7200.12, same problem, installation can't see this HDD

Multibeast
p55-DSDT isn't in installation program

i'am at this stage and searching install process. I download P55-DSDT and wait for help.

Iboot-supported + DVD maj 10.6.0 OK installation works

at reboot
4Gb ddr3 12800 seem to be as ddr2 667
PCI lacie firewire 3*400 works
Gainward 9800 Gt512 works not fully only max=1200*1024*75
audio isn't here
ethernet OK

at this stage, it's good, but i can't reboot without iboot-supported boot-DVD
G6950 i know it is, but this p55-cd53 works

how to make fine tuning ? and reboot without iboot-supported boot-DVD ?
P55-cd53'dsdt (for I5 750) exist, so it's possible ?

i can't choose good option for Multibeast
after 5 installation process + multibeast.
