Installing OSX with more RAM

Hello, long time no see ^_^
I had recently used Leo4all v4 as I remember (10.5.4 probably)
But few days ago I bought some RAM and it didn't started even with option

Code:

---

-v maxram=2048

---

In total I have now 3GB-256MB of RAM so it will be...2816 MB of RAM
is there any way to run it or install from zero??? I can format it and install from zero, I have backuped all data ^_^
also I still can't make my graphic card to use more than 1024x768 resolution :(
My graphic card is...is...as I remember:
nVidia GeForce 6100 nForce 430
yes it's integrated on Mainboard and has 256 MB from RAM to use for now
CPU is AMD of course :)

If any more information will be necessary I will try provide them

Thank You for advance :)

If you wanna re-install. Insert your leopard boot dvd, format your partition and reinstall. I would wait for other solutions on the RAM before going for the re-install. As for your onboard card, I'm not sure it will work.

good luck

I just want to have working Leo4all with that amount of RAM as it is, if there is no solution I will put out half of GB to make it suitable for Leo4all but I hope there is some other way...maybe some magic commands or other tricks???
