Sorry my dude, if it's silk screened on the motherboard, I can't see it - all of the expansion slots are populated. None of the software I tried reported any motherboard revisions, CPU-Z and HWiNFO. Their website doesn't mention anything about different HW revisions affecting V2 compatibility, only BIOS revisions.
Besides, even if it shows up with a BIOS revision older than 3.0, they have a BIOS recovery feature and you can update it. FWIW, if these boards do have a jumper that disables IME, I sure as hell couldn't find it. Have flashed the BIOS twice without jumping the non-existent header with no ill effects. Disabling IME in the BIOS makes Windows BSOD and reboot.

BIOS Recovery (see user's manual for details)

Recovery BIOS with a USB Drive
If the BIOS file is corrupted and the system is not able to boot up, this feature will allow you to recover the BIOS image using a USB-attached device. A USB flash drive or a USB CD/DVD ROM drive may be used for this purpose. Please note that the USB hard disk drive is NOT supported at this moment. Follow the procedure below to recover the BIOS.
1. Use a different system, copy the standard BIOS binary image file into a USB flash drive or a writable CD/DVD disc's Root Directory, and rename the file to “SUPER.ROM”.
2. While the system is turned off, insert the USB device that contains the new BIOS binary image (“SUPER.ROM”).
3. Right after powering on the system, press and hold <Ctrl> and <Home> keys together until the USB device's LED indicator comes on. This may take a few seconds or up to one minute to start the process.
4. Once the USB device's LED is on, release the <Ctrl> and <Home> keys. The system may generate beep codes to indicate that the BIOS ROM firmware is being reprogrammed, and a message may also be displayed on the screen. DO NOT INTERRUPT THIS PROCESS UNTIL IT’S FINISHED!
5. After the Boot Sector Recovery Process is complete, the system will reboot automatically.
6. Boot into USB drive again. When DOS prompt appear, please type AMI.BAT BIOSname.### to start BIOS update, just like in standard procedure.
7. Do not interrupt the process until the BIOS update is complete.
8. After you see the message of BIOS has completed the update, unplug the AC, clear the CMOS, and then plug in the AC, power on the system. Go to the BIOS configuration, load the default setting, save and exit the BIOS.
Notes:
** There will be additional beeping after flashing the BIOS, due to the JPME1 and JPME2 jumper location changes.
*** If the BIOS flash failed, you may contact our RMA Dept. to have the BIOS chip reprogrammed. This will require shipping the board to our RMA dept. for repair. Please submit your RMA request at http://www.supermicro.com/support/rma/.
If it interests you, I've been playing with modifying the BIOS - trying to get PCI-e Bifurcation actually working. No luck with that yet, but now I can see the AVAGO LSI menus that should normally appear in EFI mode (according to Avago). Not really sure why they do now, and why they didn't before.
Since I was risking bricking the thing in the first place, I hard-coded every instance of "UEFI Only" to "UEFI
First" - an option that isn't normally visible. Supermicro only gives you the option for UEFI Only or Legacy Only. That's kind of annoying because I'm using a mishmash of stuff, my Radeon Pro only has a UEFI OpROM, it is completely non-functional in legacy mode - and since I'd jumped the onboard VGA to disabled, resetting the BIOS meant no video or no post unless I re-enabled it or IPMI worked to change the BIOS to UEFI Boot. My MegaRAID card works fine in UEFI mode, but I was left without access to it pre-boot. Now it's integrated itself into the EFI menus.
I haven't tried booting anything that only supports MBR/BIOS booting, and the MegaRAID BIOS (and the Intel RSTe one) still doesn't show up on screen because it's a legacy OpROM and I'm not using the onboard video. Oh, and now the splash screen no longer looks like this:
It looks like this:
