https:\/\/ftp.hp.com\/pub\/caps-softpaq\/cmit\/linuxtools\/HP_LinuxTools.html<\/a>, HP supplies us with a nice .tgz file that contains several RPM’s and a few utilities that have been nicely compiled for other Linux distributions. Installation is rather easy:<\/p>\n\n\n\nwget https:\/\/ftp.hp.com\/pub\/softpaq\/sp143001-143500\/sp143035.tgz\ntar -zxf sp143035.tgz\ncd hpflash-3.22\/\ncd non-rpms\/\ntar -ztf hpuefi-mod-3.04.tgz\ncd hpuefi-mod-3.04\/\nmake\nsudo insmod hpuefi.ko\nsudo mknod -m 644 \/dev\/hpuefi c `grep hpuefi \/proc\/devices|cut -d ' ' -f 1` 0<\/pre>\n\n\n\nSo there we are: our kernel module has been loaded and a device is available. If we go back up one directory, you’ll notice that there is another tgz-file there, called hp-flash-3.22_x86_64.tgz<\/code>. This is full of hp-flash<\/code> utilities, compiled for several Linux-distributions. You can find, for example, hp-flash.u2204<\/code>, hp-flash.rh610<\/code>, hp-flash.sled15<\/code> among others. A nice install.sh<\/code> script could help you put these in the \/opt\/hp\/hp-flash\/bin\/<\/code> directory, should you be interested in that.<\/p>\n\n\n\nNow I’m actually quite lazy and not willing to clutter my system with proprietary HP utilities, so I will not run the installer script. The hp-repsetup<\/code> utility is what is needed for BIOS functionality and as I’m running Ubuntu 22.04, I’ll just run the hp-repsetup.u2204<\/code> utility right from the builds\/<\/code> directory.<\/p>\n\n\n\nAfter this, things are quite easy.<\/p>\n\n\n\n
Reading all BIOS settings can be done with hp-repsetup.u2204 -a -g biosfile<\/code> – where the -a<\/code> option means “write ASCII”, the -g<\/code> is for “get” and biosfile<\/code> is where the output will be stored. If you leave the -a<\/code> out, the output file is written as Unicode UCS-2, which can be edited by vi<\/code>, but will not show up nicely in less<\/code>.<\/p>\n\n\n\nNow you can edit the fields that you want to change, by editing the biosfile<\/code> that you just created with an editor of choice. Simply put a *<\/strong> in front of options that you would like to enable. Then run hp-repsetup again, this time as hp-repsetup -a -s biosfile<\/code> – where -a<\/code> is still for ASCII and -s<\/code> is for “set”. You don’t have to set everything at once, it is also possible to just change a single setting. For example, make a file \/tmp\/newsetting<\/code> that only contains:<\/p>\n\n\n\nWednesday\n\t*Enable<\/pre>\n\n\n\nThen use hp-repsetup.u2204 -a -s \/tmp\/newsetting<\/code> to just have the PC autostart on Wednesdays.<\/p>\n\n\n\nImportant Wisdom: as far as I can see, the “language” setting does not interfere with the hp-repsetup<\/code> BIOS output, i.e. if you change your BIOS language to Traditional Chinese, your settings in hp-repsetup<\/code> will still be English. (Tip: should you want to test this yourself, please use a language that you can revert from without calling HP support!)<\/p>\n\n\n\nThe hp-repsetup<\/code> script<\/em> (as opposed to the hp-repsetup.u2204<\/code> program<\/em> that I’m running) does a few more things: it runs modprobe hpuefi.ko<\/code> and re-runs the mknod<\/code> command with a script that it (most likely) installed during install phase; afterwards, it unloads the hpuefi.ko<\/code> kernel module from memory again.<\/p>\n\n\n\nAs said, I did not install and I’m only doing this once, so I’m not too interested in putting this somewhere on the system, but your situation could be different.<\/p>\n","protected":false},"excerpt":{"rendered":"
