Installing a Fuel VPro graphics board in an Origin 350 server results in change to the PROM system type - the PROM identifies the system as an Onyx 350 InfinitePerformance. Because the Onyx350 InfinitePerformance and the rackmounted version of the Tezro appear to be identical from a hardware standpoint, bri3d was curious if the procedure could be taken a step further; converting the Origin350/Onyx350 into a Tezro Rackmounted Workstation.

The Tezro was codenamed Chimera, and so is the O350 (according to PROM settings).
In addition, there's a PROM flag to switch between a "ChiBlade" and a "Rackmounted Workstation" (which seems to have no effect on my system - I've tried both settings and they stick but don't seem to do anything) - so I think we've got it.
Now someone just needs to grab a V12 and try it!
Caution: There is a element of risk involved in this procedure - do not attempt it if you aren't will to risk a fubar'd system. This procedure *will* erase your system serial number. An L2 Controller *might* restore your system serial number, but there are no guarantees.I had an Origin 350 with a V12 installed, which resulted in the PROM displaying the Onyx InfinitePerformance boot screen. I elected to test bri3d's suspicion that the presence of the VPro might make it possible to 'convert' the PROM machine type from Onyx InfinitePerformance to Tezro Rackmounted Workstation <with the L1 command "make rmws 1"> :
When the L1 rebooted, the 'brick' command returned:
Code:
rack: 001, slot: 01, partition: none, type: Rackmount WS [2MB flash], serial:NME262, source: EEPROM
... followed almost immediately by
An L1 "serial all" revealed the System Serial Number was blank <with a "P" prefix; P0000000>.
At this point you'd have no method of recovery unless you have an L2 Controller. I do have an L2 controller already configured with the original Mxxxxxxx serial number for my Origin 350. An L2 controller configured to work with Origin 3x0 systems <meaning it has a valid "Mxxxxxxx" serial number> should automatically assign that serial number to connected O3x0s with blank system serial numbers.
It is possible to change L2 Controller serial number <and serial number prefix>. So it
should be possible to use the L2 "serial set <string>" command to set a "P" prefix serial number in the L2, then use the L2 controller to assign that "P" serial number to the Origin 350 with the blank rmws serial number. If successful, this would create a system that would appear to to the PROM as a Tezro RackMounted WorkStation <rmws>.
Because I hope to be able to expand this system in the future <the rack mounted Tezro is limited to a single peer connection>, I elected to return the system to it's original serial number with the L1 command "make rmws 0" followed by another "reboot_l1". When the L1 rebooted the L2 discovered the blank serial number <without the "P" prefix"> and re-wrote the original system serial number. The L1 command "brick" again returns
