Kalyway works but only with cpus=1

[ismaelgualdi3]

Hi.

 

This is my hardware:

945GCT-M (v2.0) Motherboard

Intel Core 2 Duo E4600 @ 2.4 GHz

2 GB DDR2 RAM

SATA HARD DRIVE

ATA/IDE DVD-R

Integrated Intel Graphics Media Accelerator GMA950.

 

The first time I tried to start leopard install with the Kalyway 10.5.1 version, the system restart and restart. Then I write cpus=1 and the install loads. In the personalize option, if i dont check SSE2_SYSTEM, after the install, leopard doesnt start.

 

So I need to enable sse2_system in the install and write cpus=1 every time I start with leopard.

 

How can I solve theis?

 

I have "Execute Disable bit" enabled.

Could be a problem my ATA/IDE DVD-R?

 

Thank you.
