Bios update in Ubuntu!

I just updated the Bios of my DELL XPS 420 using Ubuntu. Dell’s Instructions are mostly wrong. I figured I would correct them…

1. Open a terminal and type:

sudo getSystemId

System information similar to the following information will appear.

Libsmbios:    0.XX.X
System ID:    0x00XX
Service Tag:  XXXXXXX
Express Service Code: 0000000000
Product Name: Dell XX0XX
BIOS Version: 2.3.2
Vendor:       Dell Inc.
Is Dell:      1

The important part is the line labeled SystemID. Make a note of the value or copy it into your paste buffer.

2. Go to Dell’s repo of BIOS headers http://linux.dell.com/repo/firmware/bios-hdrs/

3. Search for the directory labeled system_bios_ven_0x1028_dev_[YOUR SYSTEM ID]_version_BIOS_VERSION and click it.

4. Download the bios.hdr file (in Firefox, right-click and select Save Link As…) and note where you saved it.

5. Back in the terminal, type

sudo modprobe dell_rbu
sudo dellBiosUpdate -u -f /path/to/bios.hdr

Then reboot to complete the process.
