I installed the iDeneb v1.3 10.5.5 in my laptop:

eMachines D620-5777
AMD Athlon™ 64 processor 2650e (512 KB L2 cache, 1.6 GHz, 800 MHz FSB, 15 W)
ATI Radeon™ X1200 Graphics
Ethernet LAN Marvell 8040
Wireless Atheros XB63
160 Gb HD
2 GB RAM DDR2 667 MHz

I installed customized with this options:
Kernel 9.2.0 Speedstep
AMD Patch
Chipset VIA-SB
Ethernet SKGE Marvell
Wireless Atheros Wifi Adapter
Fix CPUs=1 -fix

It finished the installation and boots ok, the problem it is that it shows the Configuration steps Country, Keyboard, and Transfer Options (I choose Do not transfer my information now) and when I click continue it shows the same screen again and ask for the country, keyboard and transfer options again.

What can I change to pass this step?

Check the FAQ in this forum, check the second one to fix this issue, btw your telling to ur installation to use one core by default and another thing, is your chipset VIA?

Thanks that option worked good.

About the Chipset, no I think it is an ATI Chipset. Does it affect to use that option? Should I remove it?

What it is not working it is:

Sound
Network
Wireless
Can't play DVDs....

I will look for this problems on the forum.

Thanks

Whats your Audio Chipset? and Wireless chipset? what do you mean cant play dvds? and finally did you try using osx86 tools to get your drivers?

Audio Chipset: Realtek ALC268
Wireless: Atheros AR5007EG

I try to play a movie DVD and it says that the DVD was not configured (or that it can not play it).

No I didn't try using the OSX86 tools to get the drivers, because I can't connect to the network.

For audio try this
