that's a good point, and i wouldn't be surprised if it were true. FreeBSD is a bit primitive by modern standards.
that could be nice, but since my machine is running headless, i just reconfigured it to output to serial console. if i ever need to interact with it directly, i just need my laptop (which has monitor + keyboard/mouse) and a serial cable/usb adapter.I was thinking it would be nice to have a VGA port since DisplayPort is not always available on the older monitors and based on HP documentation t620 machines might have a VGA+1 serial port instead of 2 serial ports. There is a 16-pin VGA connector on the board, however ribbon cable for this does not seem to exist.
There is a post on HP website from a while back asking about same thing
HP T620 Plus – need VGA ribbon cable - HP Support Forum - 5890670
i must be the king of unable to boot T620+ machines....So after going to update my in-use t620's BIOS and realizing what a PITA it is, I developed an easier way. Some posts and HP readme's reference an easy to use "flash ROM" option in the BIOS, but none of my T620's have had this. note: all the below applies to both the t620 and t620 plus, same BIOS for both
Also, HP's site is a ****ing mess, as always (I do not miss having to use their servers). If you run through all the OS options on their drivers download page, it turns out the very latest BIOS version (released four months ago!) - v2.17, is hidden under "windows 7 embedded" - because it's HP and **** you that's why
I noticed the BIOS download comes with an EFI shell application to update the BIOS, so I simply used the open source EFI shell bin from the EDK2 project - https://github.com/tianocore/edk2 to create a bootable EFI shell image, and stuck the HP bios update efi application in the root of it, renaming it to update-t620.efi - I then wrote all this out to an ISO file linked here: http://fohdeesha.com/data/other/t620-bios-v217.iso
so just use your favorite tool to write that to a USB drive (GPT or MBR, doesn't matter), and EFI boot the thumb drive on the t620. Make sure EFI boot devices are enabled and secure boot is disabled in the bios settings. It'll boot to a simple EFI command line - just type update-t620 and it'll begin the BIOS update. Once it finishes, just power off/reboot and remove your flash drive
thanks... that's pretty much what i did right after posting the above. that seems to work just fine. thanks!I'm not sure, dd might not work with the ISO I made. I only tested writing it on windows with Rufus, but it worked with both MBR and GPT format type.
If you don't have access to windows you can create one from scratch, just format the flash drive to fat32 and make sure it's empty.
Then create a folder on the root of it called "EFI", then inside that create a folder called "Boot". Then inside that Boot folder place these two files: index - powered by h5ai v0.29.0 (https://larsjung.de/h5ai/) (right click and save as on each file to save it unmodified somewhere on your PC)
So final result should look like this, assuming the flash drive is drive G (forgive the windows parlance): G:\EFI\Boot
then in that final Boot folder should be those two files
