Trying to add Firewire card

[Radman01]

Hi all, I haver been having major problems with trying to add a Firewire card to this HP PC. Every time I plug one in and boot up the system, I get an error message and the PC won't boot. If I remove the card the PC works fine. I have tried FOUR different Firewire cards, from the $20 ones up to the $80 ones, and *none* of them will install. The error code I get is "Kernel_Security_Check_Failure", but this is not on Microsoft's website so I have no idea what to do. ANY help would be *greatly* appreciated! Thanks....and btw, the latest card I bought is the StarTech 3 port 1394 PCI Express card that was recommended on here from a previous post -- it's the $80 one!  🙂

Hey Radman,

we use HP - Workstations in professional style.

We expected the same issue like you.

It occured since Update

KB5014023 02.June.2022 — 2. June 2022 – KB5014023

Was installed... every time we trie to install a Thesycon driver or Windows tries to install there own Driver: Bluescreen Kernel Security Check failure...

Used Chipset  from Texas instrument XIO2213

Solution: Turn off DMA-Protection in Bios.. but this is not a practicable Solution for us..

Thanks for that info, *but*...I got into the BIOS on this PC, but it is the weirdest-looking, bare bones BIOS screen I have ever seen. BTW, there was no option to turn DMA protection on or off. In fact, there were very few options to do anything. I think HP has stripped down these PC's so that we can't do much of anything with them as far as changing any parameters.
