HP xw4600 Base Model Workstation

My mother board took a hit from a lightning strike to the internet cable providers line, Cooked Modem and router, replaced all. Got the 5 flashing red led code, followed the troubleshooting guide and narrowed it down to the mother board. Ordered a refurbished motherboard and installed it. System boots but cant get past the error. Downloaded the microcode and bios files to a USB using my laptop. when I select flash system rom (usb inserted when powered up) I get not found or file bad. The only peripherals connected are monitor, key board and mouse. I even tried a CD with the update installed on it. I think I'm missing a step. Any help would be greatly appreciated. HP chat support said I installed the board wrong and to take it to a service center. I cannot afford to do that at this time. Thanks!

Please read the following if you have not already

https://www.isunshare.com/computer/how-to-fix-1801-microcode-patch-or-upate-error-in-hp-business-foc....

 

Check that your USB flash is 32gb or smaller.   Some old computers cannot handle large flash.,  If you have 2gb use that size and format fat32

 

bios is here but you probably have download already

(Old core 2 duo motherboards needed a bios upgrade to do "quad" and a "mod" to use Xeon cpu)

 

Use RUFUS or whatever tool you used before to create a freedos bootable USB.  Do not select UEFI nor GPT when creating

Copy 7F3_0134.bin to the flash drive

Insert the USB, power on, and try the HP BIOS method listed above.

 

The microcode update cannot be done this way.  It is possible that the microcode in the bios above will work.

If the system can boot into the bios without error, verify your CPU.

If the bios was update but the microcode problem still exists then copy all of the following

to the USB flash.  

 

using the windows file explorer select the file "Micro Code Flash.htm" and read the instructions

 

Post back here if still having problems.  Worse case is buying the cheapest old core 2 duo to boot up and allow the update to run under windows.  I had to do that once.  Depending on who you got the motherboard from you might ask them to loan you a CPU to do the upgrade.
