Otherwise, if the chip is soldered there may be a SPI header on the motherboard. Fortunately the chip is socketed so no soldering is required. The BIOS firmware is stored on a serial flash chip on the motherboard. Legacy BIOS is 16-bit and limited to 1 MB of memory.

UEFI is a big improvement over legacy BIOS which dates back to the first IBM PC’s created in the 1980’s. There can be enhanced boot speeds and some even provide Internet access and games. It implements secure boot which can help prevent malware from hijacking the boot process. UEFI increases maximum hard drive size from 2.2 TB to 9.4 ZB (zettabytes).

UEFI typically sports a friendly graphical user interface with animation as opposed to text-based keyboard only. UEFI (Unified Extensible Firmware Interface) is a specification for a more robust version of BIOS which addresses many of its old predecessor’s short comings. This newer PC has a UEFI BIOS which complicates things a little bit. However, that tutorial featured a traditional BIOS.

You may want to check it out because it goes into more detail about the BIOS and shows a low-cost programming solution using a Pi. In my previous BIOS tutorial I repaired a Dell with a bricked BIOS using a Raspberry Pi and FlashRom. Their conclusion was a bad motherboard (out of warranty) and they estimated $500 to fix it (includes shipping) assuming that it was the actual problem.Ī little online research indicated that reboot loops are a common problem with the ASUS X99 motherboard and one possible cause is a corrupt BIOS firmware which could be remedied with a BIOS upgrade, which is more difficult to accomplish when the computer won’t boot. None of the aforementioned corrected the rebooting loop. We disconnected all the peripherals, spent a lot of time moving RAM sticks around, tested the power supply, disconnected the CPU and removed the graphics card. Is not getting past the POST (Power On Self-Test) so the CMOS is not accessible. After a few more seconds it powers back on by However, a few seconds later it shuts off. Upon power up, the computer lights up, fans The computer is stuck in a rebooting loop. Both the CPU and the graphics card are liquid This model has an Intel i7-6850K CPU running at 4 GHz with 32 GB of DDR4 RAM and a GTX 1080 graphics card.

The broken computer is made by Digital Storm which is a Silicon Valley company specializing in performance computers.
