I am a UEFI/BIOS developer. We UEFI PXE boot dozens of times per night. We have run into this error more than a couple of times. We have also done thousands of UEFI PXE boots with debug statements to prove that the patch works.

Sometimes the UEFI memory map changes between GetMemoryMap() and ExitBootServices(), making the MapKey value incorrect. Per the UEFI spec, the memory map should then be fetched again and exiting retried.

hi - if I sample from a normal distribution with something like n100<-rnorm(100,0,1) and add an outlier with n100[10]<-4 then qqnorm(n100) visually shows the point 4 as an outlier and calculating the probablity of a value of 4 or bigger in 100 samples of norm(0,1) gives > 1-exp(log(pnorm(4,0,1))*100) [1] 0.003162164 If I have more than 1 sample above outlier threshold the math is a

From: Sylvain Gault <sylvain.gault at gmail.com> On some architecture, including my hardware, the function ExitBootServices may need to be called twice in order to successfully exit the boot services. As stated by the UEFI spec, the first call to ExitBootServices may perform a partial shutdown of the services. It seems that during this partial shutdown, the memory map can be modified, thus

https://www.asrock.com/nettop/index.asp Asrock has a series of Intel and/or AMD based mini-pc's called the DeskMini. Competes in the Intel NUC space. Plenty of power and up-to-date components, multiple ports for dual monitor and at least two ssd's, etc. I don't work for Asrock or sell their equipment.

Hi folks, I am able to install workstation successfully on a dedicated SSD w/ GPT partition w/ UEFI boot using the latest `CentOS-8.2.2004-x86_64-dvd1.iso` from a bootable pen drive.

Yes, I think so. The integer really means the same as EFI's ExitBootServices. Matt Fleming <matt at console-pimps.org> wrote: >On Fri, 02 Aug, at 07:50:57AM, H.

Hi, I have just upgraded my computer to Intel Core i5-4430 Quad Core @ 3.0 GHz (supports VT-d), ASRock B85M Pro4 micro-ATX LGA1150 motherboard (supports VT-d), 8 GB Kingston DDR3-1600 memory and Cooler Master Elite 311 ATX casing (all for SGD$501). I made my computer upgrade on Independence Day 4th July 2013. I have also flashed the UEFI BIOS of ASRock B85M Pro4 motherboard to version 1.50.
