At the time, I thought I was saving myself the trouble of tracking down all the minute details pertaining to compatibility, but no such luck. Now, it actually seems easier to find data sheets on individual components (motherboards, CPUs, GPUs, and the like) than on the total builds offered by Dell, HP, Lenovo, and the like. The problem with the large assemblers is that their supply chains vary enough from run to run that the fine details about individual components are often not readily available, at least not on the used market. Sellers typically don't know how (or don't want) to give me the identifying information on their machines before purchasing, so all I could do is cross my fingers and roll the dice, which I'd rather avoid as much as possible from now on. But all of this may only apply to the used market. I can't speak to buying new, as I've only done it once or twice, decades ago. Meanwhile, my interest in hardware has been rekindled, now that I better understand some of the privacy and security implications, and I've been inspired by the open-source hardware community to learn more by doing. So, I've decided to build with the KGPE-D16. Thus far, I've got the motherboard and two 6386SE CPUs with air coolers. I buy the other components when the pricing is favorable. Later, when I've got the machine built, I'll figure out how to flash the BIOS. I know it isn't difficult, and I think I've got some good instructions bookmarked. I just haven't done that before, so it will be a learning experience. Like you, I am a tad concerned about how old the KGPE-D16 is, but it and the 6386SE are both a bit spiffier than the kit in my Z800s, and I was planning on riding them into obsolescence. So, my "new" build should have a bit more life in it than the Z800s, it will support Qubes 4.0, and I will gain the privacy and security benefits from using coreboot. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Wow! @Yuraeitha & @billollib! Can we sticky these responses? I mean, I know this is a a distribution list and not a discussion forum, but daum! Wish I could write responses like yours. I don't actually have much to add. I use Qubes for everything that I care about. I only use Windows for stuff that I use so seldom that I haven't figured out how to do it in Qubes. Insofar as I'm limited in Qubes, it's on account of my own laziness or real life issues rather than any inherent limitation in the OS. And I'm a total hack-job when it comes to computers in general, Linux, or Qubes OS in particular. How I wish I could take a good course in whatever makes Qubes tick! Alas, I'm just an end-user. Not much more to say. Just love Qubes. Don't need to do much else. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Will 4.0 work without those features, > or must I get a new machine to run 4.0? Thank you for the confirmation, @awokd! Thanks also to @Brendan & @Taiidan for the laptop recommendations as well. I've known about the G505S for a while now, but the W520 is a new option for me to consider. Meanwhile, the machines I'm currently replacing are both server workstations with 96 gigs of EEC RAM. I'm looking to upgrade to something comparable, and I'm pretty certain at this point that I'll start building with either the KCMA-D8 or KGPE-D16. I've got one year after the release of 4.0 to make the transition, so I've got time to collect all the bits before 3.2 reaches end-of-life. It's just too bad that the Z800 turns out to have a manufacturing defect. I bought them last year because they meet the minimum requirements for Qubes 4.0; or, they would have if they hadn't been borked at the chip factory. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

The only documentation I've found was forwarded to me from another user on this list. It explains a solution that Zen recommended for this particular hardware problem; but as far as I can tell, the best-available fix is still not capable of resolving the issue sufficiently for Qubes 4.0: https://support.citrix.com/article/CTX136517 -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] Qubes 4.0 without IOMMU/VT-d/AMD-Vi or Interrupt Remapping
I installed Qubes 4.0-rc4 on a machine with hardware that cannot support the following two features IOMMU/VT-d/AMD-Vi Interrupt Remapping The installation went fine. I simply continued installing after the error message appeared just after the installation ISO completed its hardware check. After installation, I was able to boot up to the desktop without any errors. I didn't do much additional testing because I thought that there might be a way to configure the BIOS on my machine to support the missing features; but alas, there is no such way. Consequently, if I ever want to run 4.0, I am left with the following two choices: A) Install 4.0 on this machine and live without the missing features. B) Get a new computer that supports the missing features. I prefer option A. Can anyone tell me what I might expect without IOMMU/VT-d/AMD-Vi and Interrupt Remapping? I've heard that PCI passthrough won't work, but I could live without it. What other problems might I encounter? Will 4.0 work without those features, or must I get a new machine to run 4.0? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

One other clue: Someone on the HP support forum suggested that the problem might be related to the x58 chipset and sent me a link to a data sheet: https://www.novell.com/support/kb/doc.php?id=7014344 I'll be reading that data sheet more closely later today, but my current impression is that solving the problem would take a BIOS patch. Or maybe the chip firmware can be flashed directly? But even if it could, the underlying instability might remain.
