Many thanks, I'll give it a shot.
And by calling Broadcom's site a dumpster-fire, you just insulted REAL dumpster-fires
I think Broadcom's support site is run by the government, nothing but misinformation, can't find anything in it...
I installed my old card into a newer Z490 motherboard and the whole board couldn't boot unless I changed the bios to CSM mode, UEFI mode was a failure. I was able to change from the last "broadcom" firmware to a newrer HPE firmware, and UEFI mode actually works and the system can boot!
So excited to still be able to use my eleven year old NIC.
