Hi.

I have HP Tx2550ee. It is a HP Tablet PC running on AMD Turion X2 Ultra with the 780 chipset (ATI HD3200 built-in video)

I used iAktos v7

I used Chameleon v2.
Voodoo Kernel, and one of the SMBIOS
I used ACPI and then ApplePS2 instead of Voodoo ones
AHCI for SATA
ATI for VGA
Broadcom for WiFi

Surprisingly all went well.

Things that worked...
WiFi
Touchpad
Touch and pen input !
Audio (noisy)
Volume control buttons (including Mute)
DVD writer
USB
Webcam

Things that didn;t work...
Video Hardware acceleration (ATi HD 3200 not supported)
Touchpad tapping or multitouch gestures (Had to use touchpad buttons)
Dilaup Modem

Hope this helps.

PS I am totally new at this and as yet have not tried to solved the non working components.

Regards
Fawad
