System boots from the selection of Catalina to the login prompt in about 12 seconds. I haven’t found anything that doesn’t work yet.
hello lcoff!
i have nearly exact the same setup as you (same RAM, GPU, Wifi+BT, only difference: my CPU is i9 10900K and I use Evo 970 SSD) and i wonder why you are able to boot so quick!
My board takes 25 seconds from opencore to login-screen and its stuck for about 3 seconds on something about USB "missing required descriptor" or "power supply unavailable: assuming successful power". the rest of the 25 seconds are just running text, not stopping or waiting anywhere...
I am really interested in your BIOS-Settings if you have anything special and I want to ask which method you use for USB (because that seems to slow down my boot a bit).
Do you use the latest BIOS? have you flashed the thunderbolt-chip or is it original?
How long does your board take from power on to BIOS / Opencore?
Would it be possible to get your BIOS-profile and your EFI so I could test if my boot-speed changes with exactly your setup?
Hey
@CaseySJ, with your flashed NVM 50 on the Vision D, does your boot time increase? I noticed that on my Vision D, with the Flashed Thunderbolt NVM, the system post time increases by about 20 seconds or so. Seems that the motherboard is trying to communicate with the thunderbolt controller during post... On stock NVM, boot time is shortened significantly.
I experienced the same problem, but because flashing TB was the first thing I did, I don't know if it would have booted faster without flashing the chip. I got the board, made blind BIOS-Update to F5 over QFlash+ and than flashed the chip. My board then needed about 30 seconds from power on to BIOS. The display on the Board showed "80" for about 17 seconds of that time, and the VGA-LED was lighing most of that 30 seconds. As a side-note, I noticed that one of the network-adapters had MAC 00:00:00:00:00:00. I tried everything, resetting, CMOS-Reset, installing the firmware-Update again, remove all hardware...even with just CPU and RAM and with complete reset BIOS it still took 30 seconds to BIOS. I then decided to return the board.
Then I was more careful with the new one: I first made sure that it booted quicker with original TB-Firmware. Instead of 30 seconds, it now took about 8 seconds to BIOS, with the same BIOS-Version and -settings and the same hardware installed than I had on my old board. Then I flashed the TB-Chip, so now the config was exactly like on my old board, and it still needed only 8 seconds to BIOS.
I guess 8 seconds is still not really fast, but its better than waiting 30 seconds...and now the hex-codes on the board's display just run through, its not pausing anymore at "80", not even for a second.
I also noticed that a Diff between the TB-Firmware-BIN of my first (broken) board and the modified Firmware-BIN from here showed a lot more differences than a Diff between the original TB-FW of my second board and the modified Firmware-BIN from here. So overall, returning the first board was the right choice I guess.
Because you also seem to have slow boots: do you have a valid MAC on both of your network cards? is your board pausing at a specific code while it boots? how many differences do you see in your thunderbolt-firmware compared to the modified one? I attached my TB-Bins from my first and my second board for you, if you want to compare.
I don't know if this helps to get more knowledge about the slow boots, but it looks like there is the possibility that thunderbolt-flashing (or something else, maybe not directly related to TB) has an impact on POST/boot times.
