Hi, here is the information from flashrom -V, lspci -nnvvvxxx, superiotool -deV.
BIOS link is herehttp://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12454&prodSeriesId=3211220&prodNameId=3211221&swEnvOID=1093&swLang=13&mode=2&taskId=135&swItem=wk-69243-1 . Not sure if it matters at all, but this machine is also supported under RHEL 3 & 5 (neither of which I am running).
I have attached the output from the other commands.
