    HP P410 controller failure

    I'm trying to make this P410 work, but it behaves strangely. I must say I'm not using HP hardware to test it, but rather a Dell motherboard. When I use the card with the cache module and battery attached, it gives me a failure message and doesn't go any further. The boot does not complete...

    X570 chipset/UEFI BIOS and HBAs

    I recently built an AMD desktop (Ryzen 5, X570 chipset) and wanted to add a little bit of local bulk storage (aiming for a RAID5 or 6 hardware setup). The BIOS is set to UEFI+CSM for backwards compatibility. I tested many of the HBAs I have, and all of them act weirdly. I should say that all are...

It is running off a Linux box, the details of which are unimportant - let me just say that the services I want are already up and running and are perfectly accessible from within my home...

    PSA: repairing "dead" IBM M5015 SAS card

    Hi, this is my first post, and it's meant to document what I did to repair one of my M5015 cards that was apparently dead. The card used to work fine, until a reboot. After that, the card seemed to have completely disappeared. No POST banner, did not show in BIOS, undetected by lspci. Thanks...
