Sun bootROM Images and OBP Firmware Patches

Compiled by Craig Dewick

Welcome to my Sun bootROM image and OBP firmware patch archive. If you have any bootROM images, OBP firmware patches (for Ultra systems), or snippets of information which aren't shown in the tables below, please email me with the details.

Starting with the sun-4c series, the OpenBoot numbering convention has been used, which comprises a major revision number, followed by a '.', then a minor revision number. The minor revision numbers are sequential decimal numbers running from 0 to 9, then 10 to 19, then 20 to 29, etc. For example, the version 2.12 bootROM for the Sparc LX is a more recent version that version 2.9. Current OBP firmware versions for the Ultrasparc-III systems are in the 4.x range for SunBlade systems and the 5.x range for SunFire systems (not yet featured here)...

From the Ultra-1 (aka A11) and up, the motherboards have featured flashROM's instead of regular EPROM's, so they can be field-programmed using special software. All older systems cannot have their bootROM's field-programmed!.

Sun has released a number of OBP firmware patches for most of the Ultrasparc systems. I'm currently in the process of obtaining the most up to date of these patches for each of the different classes of Ultra system to include here. Some of the patches are very large (5 MB and bigger), so downloading them may take quite a bit of time.

To find OBP firmware patches not available from here, you will need to go to SunSolve.

The table below lists bootROM images and OBP firmware patches that are currently available to download. Make sure you check the columns on the right hand side of the table and read the notes, etc. shown there.
