Thank you zep. You really made it easy.my installation was smooth and got finished in 19 min :)
after booting into mac i came to know.my audio,lan card and graphics (working in default res) are not detected.

while installation i choose customize and selected NVinject for XFX-Nvidia 7300GS and for audio i selected all since i don't know what to choose (bad idea..) .after booting into mac i got some error for those plugins which i selected for audio and then i deleted those kext file in system\library\extensions.Now no errors as well no sound.

for video lex23 made a post.but no joy for me.still in same default resolution.

ok try this http://rapidshare.com/files/93693717...0.pkg.zip.html

Ya, an 8139 is a 10/100 chipset. If you want gigabit, get an RTL8169 based card. Airlink101 and Trendnet cards generally use the Realtek chipsets. Look at newegg.com or frys.com.

Did you find "beta4some861_880Installer" at insanelymac,com? That'll make your onboard audio work.

sigh - here it is... Go down through Taruga's post:

eddie thanks for the build. But when i installed it system become unstable. it didn't booted successfully. Got an error saying reboot your system pressing power button.

then i reinstalled mac. selected nvinject 10.5.2 kext and nvinject.kext. everything went good. now resolution is okay

i bought a RTL 8139 Lan card.now ethernet is working.Thanks cgsheen
