I apologize for what might be slightly off topic, but I'm desperate. I ordered the parts on page 1 (except a I7 10700) and have have been trying to assemble them. Right now I'm at the stage with the cpu, 1 stick m2 storage, 1 memory stick. When I hook up the power, I get a brief flash and nothing else. I've swaped motherboards, cpus, power supplies, M2 storage and memory DIMM. No difference. What am I doing wrong?
(for reference, I had no trouble building the flash drive for doing the install, but obviously I cant do that until I can get something to turn on.)
And yes I tried googling for this issue and got nowhere...
Hi!
I've been following this thread during the last few days as I'm putting together a dual boot system (10.5.7/W10) per request of a client (Z490 Vision D + I7-10700.)
@CaseySJ's work is just great... this is one of the most accurate and robust guides I have ever come across hands down. The 10.15.7 installation on itself went really smooth, so thanks for your time and generosity.
With that being said, the motherboard's being a bit rebellious, so this might help you @
lcrl and any other user who faced/is facing any non-macOS related issues. I might have to RMA it, but wanted to hear from all of you first.
Stock BIOS (F2) wouldn't POST with a M2 drive plugged into any slot other than
M2P_SB (the one furthest from the CPU.)
The system halted with code 00 and a red led on VGA when trying to boot from any of the other two slots. It also did not boot with two drives connected, even if one was plugged into the functional M2P slot.
Also XMP profile 1 puts me on a bootloop.
===========
I updated the BIOS through Gigabyte's Windows utility, called APP Center (wish I've done it manually with Q-Flash, but I didn't have a suitable flash drive) and that left me with the F6 version, which enabled the other two slots. With both of the M2 drives now fully operational I went on installing macOS following CaseySJ's guide, so
update the BIOS if you haven't done so by now.
===========
The downside of all this is that the update had a negative impact on what I think is USB management, as it takes at least 20 seconds for the system to get past the Gigabyte splash screen and into the bootloader when a USB peripheral is plugged into any of the 3.x ports. After that, both OSs boot normally and fast from Opencore.
If I boot with a device plugged into a 2.0 port, the BIOS time gets reduced to 8 secs.
Catalina is really stable. Windows, on the other hand, threw a few assorted BSODs (ntfs.sys, tcpip.sys, Page fault in nonpaged area, Critical process died) but after some updates it seems to be doing better. An Unknown USB Device with descriptor request failure is shown on the Device Manager whenever a device is plugged into a 3.x port.
XMP has not been sorted out.
Do you guys think the mobo is faulty? macOS works like a charm...
I got a feeling that all of this is tweakable/fixable, and I don't want to swap the board. I'll try to Q-Flash to F7 ASAP.
BIOS update did help on critical aspects, so I'm gonna keep pushing things a bit forward and see where I end up.
Cheers and thanks for all the work!
