Failed to verify BaseSystem.pkg

[smallinov]

I am repeatedly getting the error "Failed to verify BaseSystem.pkg" on a GA-P55M-UD2 board. I have tried another CD drive, another hard drive, and then even pre-loaded the DVD onto a second partition. I get the same error every time. I have read a couple of other similar message but without any resolution. Someone help? Please!! :-\

Are you using a purchased retail version of Snow Leopard?

Yes I am, brand new out of the box.

I would test the RAM using memtest+.

Have you verified that all of the hardware is working correctly? Have you run memtest+?

Are you using the latest version of iBoot?

Are you using a purchased retail version of Snow Leopard?

I always set up the BIOS at the minimum for install. Disable the Peripherals like Audio/1394/Ethernet/USB-3/xTreme controlers/eSata.

HPET=Enabled and 64 bit

SATA-0 should be your DVD drive SATA-1 your HDD and set to AHCI, reboot if just set and select the P0-DVD-DRIVEINFO to boot from. It won't be available if you just changed to AHCI.

ACPI should be S3 or Auto and ACPI 2.0 enabled.

Some systems can use only 1 stick of RAM and kept under a certain size I think 2 or 4 gigs.
