Use the cursor keys to move down to the line that says linux and add the following to the end: setkeymap=uk copytoram dostartxĬhange the keymap to be appropriate for your own environment or if you are in the USA, just leave that part out. Press the e key to change the default boot options. You will come to the SystemRescue boot menu, which should look like this: Press the escape key to access the boot menu and select your USB Stick. With the jumper on the FDO pins, insert your bootable USB into the machine and turn it on. So it should look like this: Boot the machine with SystemRescue Jump the pins with a jumper cap or anything else that you can find (paperclip etc). To put the machine into service mode you will need to remove the lid and find the FDO (Flash Descriptor Override) jumper, which is here: Once you have created the bootable USB you can shut the machine down and put it into service mode. There are instructions on the SystemRescue website on how to make it bootable. Next, download SystemRescue using and make a bootable USB drive using Rufus. I’d be interested to know if this BIOS mod also works for the 6300. ROM Firmware for 8300 Elite and 6300 Pro Business At the time of writing that was version 00.03.08 Rev.A. Take a moment to check that you are on the latest BIOS available from HP. Modify the BIOS and inject the NVMe driver.īefore proceeding with the rest of the steps.Create a SystemRescue bootable USB Drive.Upgrade your current BIOS to the latest version.These computers are now really cheap on Amazon and in they are a bargain in my opinion if you just need a basic machine work school or office work. An NVMe to PCIe Adapter, I used this one from Amazon.In order to carry out this upgrade, you will need a few things: Proceed at your own risk! Required Hardware You could very easily break your machine. So I am going to add an app/fvbootstrapper that builds HOBs UEFI requires and loads UEFI FD in a few more days.This blog post contains instructions on how to modify your BIOS using a hardware programmer. I decided not to use aboot to bootstrap anymore because I want to keep FV bootstrapping simple. I manually changed BPP information to 32bit and added BGRA pixel format definition (as you did in LK) manually. So for Dragonboard 820c, I simply enabled these switches in build: DEFINES += ENABLE_DISPLAY=1Īnd the HDMI works natively (information retrieved from EDID). ![]() (Yes, I used your LK variant for bootstrapping, though I changed pixel packing format in mdp5.c to comfort UEFI BGRA FB requirement), and it boots Windows. QcomPkg contains two parts, one is target-independent library and drivers (for example, Qualcomm utilities, high-level device drivers like GPIO/I2C/SPI/SPMI, MDP display drivers, PMIC abstraction), the other is target-dependent library and drivers like buttons, PMIC chipset drivers and SoC-specific feature drivers.ĭragonboard 410c uses ADV7533, while Dragonboard 820c has HDMI natively. It’s interesting, and I can start my experiment porting a EDK2/UEFI to DB820c The conclusion is SD820’s XBL recognizes either AArch32 and AArch64 APPSBL images (not like SD410). Not really usable yet, it hangs at SEC phase (likely what I expected to see, because the platform configuration in the UEFI image looks like a modified variant from Windows Phone). Invalid memory configuration, check memory partition tableĪSSERT /local/mnt/workspace/CRMBuilds/BOOT.XF.1.0-00301-M8996LZB-1_20160715_044814/b/boot_images/QcomPkg/XBLCore/Sec.c(598): Status = 0 I removed “aboot” on purpose to see what happened. ![]() LK) presents, XBL segment 1 loads and jumps to it. The third part is UEFI itself, but if “aboot” partition (aka. XBL have three segments, in current boot workflow only first two are utilized (identical to SBL1 on DB410c). Received my board today, performed some experiments.
