Just out of interest - what chipset does your Xeon system use?

lspci of the P4 32bit desktop with 3GiB
00:00.0 Host bridge: Intel Corporation 82875P/E7210 Memory Controller
Hub (rev 02)
00:01.0 PCI bridge: Intel Corporation 82875P Processor to AGP
Controller (rev 02)
00:1d.0 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB
UHCI Controller #1 (rev 02)

lspci of the Xeon 32bit HP Proliant Server with 4GiB:
00:00.0 Host bridge: Intel Corporation E7520 Memory Controller Hub (rev 0c)
00:02.0 PCI bridge: Intel Corporation E7525/E7520/E7320 PCI Express
Port A (rev 0c)
00:06.0 PCI bridge: Intel Corporation E7520 PCI Express Port C (rev 0c)
00:1d.0 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB
UHCI Controller #1 (rev 02)

We know the E7520 is able to do the remapping, provided the BIOS does not mess it up. I have no idea about the E7210 (or the 875P - I was not aware that they were this closely related), but without checking any docs I'm assuming a 4G memory ceiling and no remapping capability.

Thank you.

lspci of the new box with 975X and Core 2 Duo not available yet for
obvious reasons (I don't have the the box yet).

I'd appreciate if you could send me both lspci and /proc/iomem output when you get one of these with 4G or more ram installed. Off list, please.

Yours,
