That's why I concluded that someone had fixed the problem in i386 but not moved it to amd64. This system has no problem with i386. The install disk boots without any special action on my part, the system installs, works great (except the x.org 7.3 ati driver doesn't support the video chipset, but VESA mode is adequate for now). > Do you know what the patch was that HP provided for Linux? I > wasn't able to find it. No, I only read some postings on Linux lists that said HP had supplied a patch that allowed HP 64-bit boxes to run Linux if your kernel was new enough. And the poster in that case may not have been entirely accurate! I think the dates were around 1st Q of this year. Of course, I can't find those postings now. > If you disable ACPI is FreeBSD/i386 able to see all of the RAM in the box? i386 can see it with ACPI enabled or disabled. Only amd64 has a problem in my case. Judging by various postings, different HP systems seem to have different details, though. At the moment I'm running i386 7.0-CURRENT-200708 snapshot on an HP dc7700 convertible (BIOS 1.10) with ACPI enabled. It reports real memory = 3757768704 (3583 MB) and ACPI APIC Table: . An amd64 install CD gets the SMAP panic with or without ACPI. I just read that HP has released a newer BIOS for this thing since I was trying to install amd64. So when I get time I will try updating the BIOS and see what happens. Before that I'll send you the files you asked for. And then maybe again after the BIOS update ;) - Bob
