Batman is now running El Capitan 10.11.4. I used UniBeast v6.1.1 and MultiBeast v8.1. The following procedures to make a successful running El Capitan installation require the use of the standard tonymacx86 DSDT with a simple modification to the DSDT. I could not get El Capitan to work properly without the use of the modified DSDT. Here's the procedures I used.
Backup-ed my Mavericks SSD to a HDD partition that I use for backups using Carbon Copy Cloner.
Created a USB 2.0 Installer thumb drive with
UniBeast using the tonymacx86
http://www.tonymacx86.com/el-capita...-el-capitan-any-supported-intel-based-pc.html choosing the Legacy Bootloader mode. I didn't need to select Intel/AMD/Nvidia since my Gigabyte 5770 is natively supported by Apple's OS X drivers.
Put a copy of
MultiBeast,
EFI Mounter v3,
MaciASL and the P55M-UD4 DSDT.aml (See Downloads menu at the top of this page for the
DSDT Database)
Change the BIOS' default boot disk to the USB Installer thumb drive which was plugged into the USB 2 port in the stack with the PS/2 port
Advanced BIOS Features > Hard Disk Boot Priority <-- selected the USB Installer
Advanced BIOS Features > First Boot Device > USB HDD
F10 to save the changes.
At the Clover boot screen, select the USB Installer drive.
After selecting English and reaching the Installer screen, select Tools > Disk Utility from the menu bar.
Prepare your installation disk by partitioning, formatting and/or erasing (I chose Erase). When completed, quit Disk Utility.
Proceed with part one of the installation which will reboot upon completion (now you know why I changed the BIOS boot drive).
Upon completion part one, chose your installation disk this time at the Clover boot screen.
Complete the second part of the installation.
Copy MultiBeast, MaciASL and EFI Mounter v3 to your Application folder and unzip all.
Before running MultiBeast for El Capitan, open the Security & Privacy Preference Pane in System Preferences (located in your Dock).
In the lower left corner, click on the padlock and type in your Admin username & password
Click on the General tab if it isn't already highlighted;
Click on the "Anywhere" radio button under "Allow applications and downloaded from:" and
Close the System Preferences window.
Run MultiBeast selecting the following:
Quick Start > Legacy Boot Mode
Driver > Audio > Realtek ALCxxx > ALCALC885/889a
Driver > Disk > 3rd Party SATA
Driver > Disk > 3rd Party eSATA
Driver > Misc > FakeSMC Plugins
Driver > Misc > FakeSMC HWMonitor Application
Driver > Network > Realtek > RealtekRTL8111
Build <--- To see your full configuration as shown below
Note: While the MultiBeast Configuration snapshot above may reflect earlier versions of some of the drivers/kexts, the .mb file will automatically be updated by MultiBeast to the current MultiBeast versions.
Save <--- Save your MultiBeast configuration file somewhere convenient
Click on the Install button in the MultiBeast window bottom right hand corner and wait for MultiBeast to finish.
After MultiBeast completes, don't reboot.
Copy DSDT.aml from your USB Installer thumb drive to the Desktop.
Run MaciASL, select your DSDT.aml. You need to change as show by toleda:
Edit dsdt/HDEF/layout-id/0x01, 0x00, 0x00, 0x00 (replace: 0x77, 0x03, 0x00, 0x00)
Note: The above is for a P55M-UD2 (0x77). in the UD4 DSDT, we'll see 0x75 instead.
Search for HDEF (Cmd-F) and, on the 2nd occurrence, find "layout-id".
Code:
Device ([B]HDEF[/B])
{
Name (_ADR, 0x001B0000)
Method (_PRW, 0, NotSerialized)
{
Return (Package (0x02)
{
0x0D,
0x05
})
}
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x04)
{
"[B]layout-id[/B]",
Buffer (0x04)
{
0x75, 0x03, 0x00, 0x00 [B]<--- Need to change this line[/B]
},
Replace the 0x75 with 0x01, and 0x03 with 0x00.
Save the DSDT.aml
Now, you need to put the DSDT in the El Capitan drive's EFI partition in the /EFI/Clover/ACPI/patched/ folder
Open the Terminal (/Applications/Utilities/) and opy/paste this command and Return:
Note the disk
xs1 of your El Capitan drive
Run EFI Mounter v3, type in your admin password and select the disk
xs1 of your El Capitan drive
Open the EFI drive and navigate to /EFI/Clover/ACPI/patched/ folder which should be empty.
Drag and drop your DSDT.aml into the patched folder.
Reboot into the BIOS and change the parameters identified above back to your Installation drive and HDD, respectively.
F10 to save the changes and leave the BIOS.
At the Clover boot screen, use the keyboard's arrow key or mouse to select your El Capitan drive.
To get audio working you'll need to use the Green sound port on the Rear Panel with the System Preference's Sound pane set up as follows:
