Coreboot is not a magic bullet. While it is open source, there are still likely to be bugs in specific implementations if an oem was to use it. Getting rid of the bios is also not exactly a good option either. With no bios, you lack a standard way to boot the system and you end up with a mess like linux arm currently is (tons and tons of system-specific configurations that make booting a generic kernel almost impossible). Also, for things like ASPM, they have to be validated on the platform. If the OS doesn't support it (IIRC, XP did not), the different combinations of hw were not likely to be validated so they may not work in practice.

Futhermore ARM is a piece of SOC crap that requires insanely rediculous configs with even basic circuitry bugs for which a rediculous erreta is always present. Needles to say that a x86 CPU is way easyer to boot. In fact, by getting rid of the BIOS, there is no need for stupid Philips audo cable connectors from the south bridge (to the RAM) to properly config the fscking RAM. John von Neumann would turn around in his grave if he were to hear this.

This site also tells a story...
"System Product Name", "System Name" and "To Be Filled By O.E.M. To Be Filled By O.E.M." are all the predefined values, and supposed to be filled in by the BIOS developers before shipping. If they cannot even fill this in....
[OFFTOPIC] HP laptops--at least, recent ones--aren't that great anyway, regardless of what OS you're running.

The ASPM-related messages from kernel can be very confusing, but there is an easy way to test if ASPM is active: Write something to /sys/module/pcie_aspm/parameters/policy
I get this on new kernels WITHOUT pcie_aspm=force:
Code:$ sudo echo powersave > /sys/module/pcie_aspm/parameters/policy bash: echo: write error: Operation not permitted

To the earlier poster with a Vaio -- which model? I'm guessing the top-line Z and S models might have a better BIOS than the ones in the budget lines.

Intel BIOS too?
My motherboard is an Intel DP55WG and the BIOS is written by Intel.
ACPI FADT declares the system doesn't support PCIe ASPM, so disable it
