El Capitan on P5LP-LE (Rev 5.03) - Installation is successful

[osx151212]

Hi,

I've attempted to install El Capitan on P5LP-LE (Rev 5.03) and installation have proceeded to the end.

After installation of Clover boot loader into EFI partition (ESP) the computer boots fine. Mainboard has build-in GMA950 which is not supported, you will require add-on video card (check compatibility list). Build-in video adapter works with some abnormalities and no acceleration -- still usable for installation.

INSTRUCTION: To install and boot system the bootloader Clover requires following configuration (EFI/CLOVER/config.plist)

<key>Boot</key>
<dict>
          <key>Arguments</key>
          <string>npci=0x3000</string>
</dict>

........

<key>ACPI</key>
<dict>
          <key>DSDT</key>
          <dict> 
                    <key>Fixes</key>
                    <dict>
                               <key>AddDTGP_0001</key>
                               <true/>
                               <key>FixHDA_8000</key>
                               <true/>  
                               <key>FixHPET_0010</key>
                               <true/>
                               <key>FixIPIC_0040</key>
                               <true/>
                     </dict>
            </dict>
</dict>

For sound it require to add into Clover's config.plist

<key>Devices</key>
<dict>
            <key>Audio</key>
            <dict>
                       <key>Inject</key>
                       <integer>7</integer>
            </dict>
</dict>

Also do not forget about following section to allow load kexts with broken signature

<key>RtVariables</key>
<dict>
           <key>BooterConfig</key>
           <string>0x28</string>
           <key>CsrActiveConfig</key>
           <string>0x3</string>
</dict>

You will require to download AppleALC.kext and put it under CLOVER/kexts/10.11

after reboot sound works with vanilla (original) AppleHDA.kext (system update will not affect sound configuration)

This mainboard has buildin NIC Intel® 82562GT 10/100 Mbps Fast Ethernet LAN PHY. I've attempted to find kext for it and so far no success yet.
