So I noticed the Windows partition cannot be mounted in rw mode, it can only be mounted in ro-mode. I did not start W10 yesterday or today, nor did I change a thing yesterday evening, it shut down perfectly from what I rememberДЇortunately I have a Xubuntu thumb drive which I used to check out the loader entries and UUIDs/PARTUUIDs of the partitions, maybe something went wrong somehow? Nope, everything is still as it was. Systemd-boot is the boot loader and the AL entry pretty much looks like this except for the PARTUUID obviously, and my entry has that intel microcode line in there When I select the AL entry in the systemd-menu, the screen basically goes black except for these blue lines at the top and bottom (which I'm somewhat sure are from the mainboard's UEFI menu itself). I am basically totally out of my depth on this one.ДЄfter months of working flawlessly, Arch won't boot up anymore as of today. If you try to use the older DOS IFLASH/2 it gives you some error about it not being an Intel board.Typing this up on my laptop. There was a new version of IFLASH/2 that came out with the 77 board series. Otherwise, no one would have seen the blue Window or the Beta fish when booting Windows 8.ДЄnd this BIO file for this Intel board can be updated using either the built-in F7 method, or by using their DOS (or Windows) tool. BUT I will say that old BIOS types that do not have the BGRT and do have the ability to add a custom splash screen will NOT be picked up by Windows 8. I didn't get a chance to compare it with a previous version yet to see if that is true. I tested this by attempting to open an Intel BIOS from May of this year.ДЇor this Intel one, I am thinking that either the BIOS splash screen is now kept in the BGRT, or it puts it in the old and the new place. Also I forgot to mention that the Intel ITK5 used to modify the DH77EB BIOS is unable to open BIOS files without the extra ACPI tables.

And by 'general use' I mean either some generic tool, or even a BIOS specific (AMI, Award, Phoenix, Insyde, etc) manipulation tool. I still can find no 'general use' BIOS modification tool that lets me put a picture in there.

Well so far, the only board I've seen this on has UEFI 2.3.1 firmware. The Intel DH77EB reveals this capability in the release notes for the 0089 version BIOS: So far I have found only 1 board that actually has this table, and it is added with a BIOS update. But I am sure you are asking what this is about? Well you know when you boot up Windows 8, you see either the blue Window logo or the Beta fish? Well if the BGRT exists and there is something in it, then that image is shown instead!

A Windows 7 install will still read whatever ACPI tables are there, but some do not show up, including the BGRT.

While a system may have the BGRT on the system, so far in my testing, this tool can only see it on a Windows 8 install. It is called Hardware Editor or Hardware Read & Write Utility. There is a tool where you can see if your hardware has this specific ACPI table. This table is only supported on UEFI systems. by a key press), the valid bit within the status field should be changed to 0 to indicate to the OS that the current image is invalidated. This should be done after it is expected that any firmware components that may write to the screen are done doing so and it is known that the image is the only thing on the screen.

The table is written when the image is drawn on the screen. The Boot Graphics Resource Table (BGRT) is an optional table that provides a mechanism to indicate that an image was drawn on the screen during boot, and some information about the image.
