Help: No way to install on ASUS P5B-VM SE (no AHCI in BIOS)

[De_Bilbao]

I'm trying to setup Leopard in this setup:

• ASUS P5B-VM SE Motherboard
  
• Intel Core 2 Duo E6600
  
• ASUS DRW-20B1LT DVD-RW (SATA)
  
• Hitachi HDS728080PLA380 (80 GB, 7200 RPM, SATA-II)
  

But I can't start the installation DVD neither with Kalyway nor BOOT-132.

 

The latest 903 BIOS doesn't include an option to activate AHCI. I'm quite sure that the Intel P965 chipset supports it, being the southbridge and Intel 82801HB ICH8.

 

Do you know about any modded version that supports AHCI setting?

Any other way to install?

 

Thanks in advance.
