HP has recently released a BIOS update for the zv6000/r4000 series of notebook pcs. This update, called F1.C, supposedly resolves an issue where users may get a Blue Screen (BSOD) error when using the USB ports and Cardbus (Express54) slot. I, for one, have never experienced this issue therefore I cannot comment on whether or not the issue is improved upon or resolved.
A side note-
I have recieved more than one email stating that after installing this BIOS update your system may no longer boot into Windows. I have not personally seen this issue. However, I have had difficulty in the past when attempting to update the BIOS using the Winflash utility — to the extent that my system was effectively ‘bricked’ and had to be sent to HP for warranty repair.
Typically, a BIOS flash can cause a PC not to boot into Windows if one of the following settings is reverted to default after being changed… or simply changes: APIC mode, ACPI settings, Power Management (S1/S3/s1&s3), and Cool & Quiet. If you are one of the ones affected by this update check these settings first.
My experience with laptops has been the following. As a general rule, **do not** update your BIOS unless your system is specifically affected by the issue that the new BIOS addresses, *especially* if your notebook is no longer under warranty. I have found through my own experiences that flashing the BIOS on a laptop is much more troublesome (and problematic) than doing so on a desktop. There are several more “technical” reasons for this, but the one I will hammer home here is this one: Most laptops do not have a stand-alone OS disk that does anything less than a complete re-format and fresh install of Windows (plus associated “bloatware”) and will not do a repair install.
I have said my piece and you’ve been warned. Now here’s the link:
