Mainboard asus p5kpl-cm, processor core2quad q8200, VGA MSI GX 710. Western digital green sata drive r120GB.
Catalina installed on external usb drive. Got soundcard working with voodoo 2.9.2, lan working with AttansicL1eEthernet.kext. rtl8811Au wifi working. Bluetooth working. Used the clover catalina folder from this site as base, I don't know anything of DSDT patching. Cleared kext folder from some unneccesary kexts. Would like to use the onboard sata controller. But when i connect the satadrive to the controller it does not boot from the disk. Diskutility is also not showing the satadrive at setup. Can you help me with this problem?
