TELVM Posted August 24, 2020 Share Posted August 24, 2020 Long story short, I've managed to install & run W7 x64 on an X570 board. No small feat. Basically followed this video: https://www.youtube.com/watch?v=A6_MdxMUpRE The heretical concoction runs amazingly well, save for a little too long boot time (about 16 seconds from the Windows 7 "meatballs" getting together to desktop, should be 1 to 3 seconds tops). Investigating with the Event Viewer I've found this: But I haven't the foggiest idea on how to deal with this gremlin . Though I suspect the beta USB 3.0 drivers for Windows 7 on X570 might be related to the problem ... Any help or ideas would be much appreciated!

Tripredacus Posted August 25, 2020 Share Posted August 25, 2020 A good explanation of the boot process by our old friend: https://answers.microsoft.com/en-us/windows/forum/windows_7-performance/sudden-slow-reboot/7e4d38c2-8c2e-4e19-a2aa-c60bb5b62b75?auth=1 Using a spinning disk or SSD? I come to think of boot time as being important only if uptime is not important. Link to comment Share on other sites More sharing options...
TELVM Posted August 25, 2020 Author Share Posted August 25, 2020 (edited) SSD (SATA3 for now; the next round of headaches will be trying to boot W7 from an M.2 NVMe one ). I can live with the extra 13 secs of boot time, but it is annoying. All my other PCs boot up lightning quick and I'm spoiled . I suspect the "special" beta USB 3.0 drivers for W7 on X570 are connected to the problem, because before them the time from "meatballs together" to desktop was just ~2 seconds. But right after installing these drivers the problem appeared and that time grew to ~16 secs: Edited August 25, 2020 by TELVM Link to comment Share on other sites More sharing options...
jaclaz Posted August 26, 2020 Share Posted August 26, 2020 Semi-random thought, but maybe - just maybe - you can tweak loading settings for that driver/service. https://docs.microsoft.com/en-us/windows-hardware/drivers/install/specifying-driver-load-order jaclaz Link to comment Share on other sites More sharing options...
TELVM Posted August 27, 2020 Author Share Posted August 27, 2020 Thanks for the idea, Jaclaz. These are the "OEM" loading settings: X570_149C_Drivers_B2\USB DRIVER\AMD_USB3.2_WinA_Beta_9.0_7052\AMDXHCI.INF [AMDHub3.AddService] DisplayName = %AMD_HUB3.DriverDesc% ServiceType = 1 ; SERVICE_KERNEL_DRIVER StartType = 3 ; SERVICE_DEMAND_START ErrorControl = 1 ; SERVICE_ERROR_NORMAL ServiceBinary = %10%\System32\Drivers\AMDHub3.sys LoadOrderGroup = Base X570_149C_Drivers_B2\USB DRIVER\amdhub31\amdhub31.inf [amdhub31_service] DisplayName=%amdhub31_ServiceDescription% ServiceType=1 StartType=3 ErrorControl=1 ServiceBinary=%12%\amdhub31.sys LoadOrderGroup=Base AddReg=WinToGo_amdhub31.AddReg X570_149C_Drivers_B2\USB DRIVER\amdxhc31\amdxhc31.inf [amdxhc31_service] DisplayName=%amdxhc31_ServiceDescription% ServiceType=1 StartType=3 ErrorControl=1 ServiceBinary=%12%\amdxhc31.sys LoadOrderGroup=Base AddReg=WinToGo_amdxhc31.AddReg Any suggestions on how to fiddle with them?

jaclaz Posted August 27, 2020 Share Posted August 27, 2020 Hmmm. No. Those drivers are seemingly Kernel drivers and SERVICE_DEMAND_START (PnP), in this case (I believe) the LoadOrderGroup is ignored. I think that you can try disabling them (setting StartType=4) without uninstalling them and see if they are the actual culprits. You can also try using loadord: https://docs.microsoft.com/en-us/sysinternals/downloads/loadorder to see how they "fit" in load order, then try changing the LoadOrderGroup to something "later" than "Base", the list is in : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ServiceGroupOrder but I don't think it may change anything Be warned, there is a risk the thingy will BSOD/hang, so have handy a way out. jaclaz Link to comment Share on other sites More sharing options...
