How to update T500 BIOS under Linux

I am trying to refurbish my old T500 which is running Linux Mint 18.2 and I can't find the latest BIOS either to update the existing one or confirm it is current.  The output of dmidecode is:

 

6FET92WW (3.22 )
# dmidecode 3.0
Getting SMBIOS data from sysfs.
SMBIOS 2.4 present.

Handle 0x0028, DMI type 11, 5 bytes
OEM Strings
	String 1: IBM ThinkPad Embedded Controller -[7VHT16WW-1.06    ]-

Advice is appreciated.

Hello and welcome,

 

If you're looking for the ISO download to check the version and perhaps install, it's here:

 

https://download.lenovo.com/eol/index.html

 

Looks like it's v3.23 or 3.25.

Re: How to update T500 BIOS under Linux

Many thanks. Would this .iso qualify as a "self-contained bootable ISO environment?" I was hoping to flash the BIOS from a bootable USB

Cheers

I'm afraid I can't answer that question.  There may be ways to manipulate the ISO to make it (or parts of it) usable on a flash drive, but I'll have to leave that to others.

 

BIOS  exe files for newer ThinkPads actually include a tool for building a flash drive but it wasn't around for these older models.

I downloaded the .iso and flashed it to a bootable USB, but it seems to be Windows-specific.

Not sure I understand.  The ISO is intended to be used to burn a bootable CD/DVD/BD.  Shouldn't be anything window-ish about it.

Indeed.  It seems something went awry creating the USB.  Burning the .iso to CD worked and so did installing grub-imageboot, storing the .iso in /boot/images, updating grub, and rebooting.  Thanks for the help.

Good news Smiley Happy

 

...grub-imageboot... That's interesting.  I've always done it by hand with stand-alone grub2 or Ubuntu's grub2 w/a manually created .cfg using loopback or memdisk.

 

I tend to keep a bunch of bootable images on a flash drive and secondary drives in my desktop and laptops.  Will have to look into that.

 

regards,

Z.

Re: How to update T500 BIOS under Linux

Just discovered that one myself.  Far and away the easiest solution.  After installing and updating, you can just select the bootable .iso image on the GRUB menu.
