For now I am beginning with two easy questions, however I assume that at the beginning I bought to report about my configuration.
{Hardware} smart, I upgraded the RAM to 22GB (from the unique configuration of 6GB), all modules 800Mhz.
At first I used an previous AMD HD 5770 with Mac firmware, then I put in an XFX FX 580 GTS (with 8GB video RAM, oddly recognised as 6GB),
utilizing a twin GPU configuration, and now I lastly managed to eliminate the previous graphic card, utilizing the boot picker offered by OCLP.
Earlier than attempting to put in Catalina I eliminated the wi-fi module from the motherboard, however the Bluetooth module did not come out.
The screws had been caught and finally I ended up stripping one among them. I discovered that I might disable it plugging an previous USB Bluetooth dongle.
Now Bluetooth appears to work.
I’ve 5 HDs, two SSDs and three magnetic. The fifth is a SATA SSD mendacity contained in the CD/DVD drawer, alongside a PATA DVD reader/burner that changed the (damaged) authentic one.
At first I put in Excessive Sierra, Mojave and Catalina utilizing DosDude patcher.
The one set up that gave no issues in any respect was Excessive Sierra. Initially the pc was gifted to me with Yosemite, I instantly up to date to El Capitan however it was virtually unusable on the internet. No appropriate browser supporting HTTPS certificates.
I made a decision to only soar Sierra and put in Excessive Sierra utilizing DosDude patcher on a distinct HD.
Putting in Mojave was tougher, however I ended up with a working set up that I nonetheless maintain to make use of 32bit apps.
Catalina was an actual nightmare. I frequently ended up again at the 1st step, restarting time and again the set up course of.
I attempted virtually all the pieces. I swapped graphic playing cards (powering the 580 externally), disks, USB/DVD set up medium, and so on and so on.
In the long run I managed to have Catalina put in, however there should be a further EFI partition , as a result of it may be booted from two separate choices within the boot picker.
One has the label of the disk it sits on, and the opposite seems completely different from all of the others and is named “EFI”.
Whereas I used to be busy with all that, I ordered a Fervi FV8303 PCI-E card with a latest wi-fi a/b/g/n chip and a Bluetooth 4.0 chip (examine the EDIT on the finish about it).
Yesterday I additionally bought a twin mini 6-pin to plain 8-pin GPU energy cable, that allowed me to eliminate the exterior PS and energy the GPU internally.
Now I’ve Mojave and Catalina on two separate disks, each out there from the OCLP boot picker.
Large Sur is put in on two different disks. One is the principle set up on the larger SSD, the opposite one has a minimal set up of Large Sur, and has OCLP EFI boot put in.
This fashion I need not have the USB thumb drive to get the boot picker.
The small (64GB) boot SSD disk sits on high of the CD/DVD drive, utilizing a molex>SATA energy adapters,
and one of many two SATA cables that I routed by means of a small gap, and are related to the 2 SATA connectors which are out there on the mainboard.
I intend to switch the 64GB quickly, utilizing a brand new 1TB SSD disk that might be both used for a Home windows 11 set up, or perhaps Monterey…
I hope my prolonged description has given an correct image of my present config. Right here comes the primary query:
can I additionally set up OCLP EFI boot on the principle SSD disk that hosts the complete scale set up of Large Sur?
In apply, I am asking if a number of Open Core EFI boot partitions can coexist in the identical system.
If I can do this, I might take away one of many two disks with none adversarial impact, and nonetheless have a bootable Open Core boot that provides me the boot picker..
Second query:
Once I was utilizing El Capitan (and possibly additionally Excessive Sierra) I had one of many 4 Mac Professional most important disk drawers devoted to a Home windows 11 set up.
All the things labored nice. On the time I had the AMD HD 5770 GPU, and I might both boot MacOS or Win11.
Since then I took the drawer out of the case, to keep away from potential interactions with all my tentatives to put in successive MacOS variations.
Right now I attempted to place the disk again, and shock shock, the Open Core boot picker can’t see it!
In fact if I load Large Sur the disk is completely seen (and readable).
Am I lacking one thing? Is there a easy technique to make the Win 11 set up out there once more?
I sort of bear in mind I learn that anyone bricked his Mac Professional booting off a Home windows disk with EFI boot.
I discover it unusual. Is it true? Any particular caveat I ought to concentrate on?
EDIT:
Plainly the FV8303 PCI-E card will not work on my Mac Professional 3,1.
I simply bought an FV-T919, which has 4 (!) antennas and likewise comes with the cable to attach the cardboard to a USB header. This card is offered as Mac/Hackintosh appropriate, so I assume I will probably be OK with it.
Thanks prematurely to whoever will probably be so mild to reply my questions.
Cheers
Paolo
