The Xenium (OpenXenium) has so many more features than the Aladdin modchip.

Biggest one being multiple banks so you can flash and boot different BIOSes. (Not that anyone needs to boot more than one BIOS but you can't try others without wiping the one 256KB bank that an Aladdin has to try another.)  Limited to using one 256KB BIOS with an Aladdin modchip.

The XeniumOS can format a new hard drive in the Xbox without any other software. Albeit, doesn't do G drive and I believe only supports 16KB clusters for a maximum size of 256GBs for the F drive.  Therefore, to properly format the extended partition(s) on hard drives larger than 250GBs, you'll have to re-format the extended partitions with XBPartitioner v1.3.

@KingLuxor's eBay listing contains a bullet list of features of the OpenXenium modchip:  (copied from there to here)

Supported XeniumOS features: (taken from project repository)
  • Software controlled BIOS bank switching (any BIOS combinations that fit into 1mbyte of flash memory (4x256k, 1x512+2x256k, 2x512k, 1x1mbyte).
  • Instant boot to a chosen BIOS using the power button.
  • Boot the XeniumOS with eject button.
  • Ability to boot from the onboard BIOS (colloquially known as TSOP booting). This will completely disable OpenXenium and release D0/LFRAME(1.6) to boot the Xbox as if stock.
  • All the standard features in Cromwell/XeniumOS. (EEPROM tools, Hard drive tools, FTP/SMB Server etc.).
  • Three general purpose outputs. These are normally bitbanged as a SPI master (MOSI,CLK,CS) with the most common use an LCD, however could support any SPI peripheral in theory.
  • Two general purpose inputs. On a Xenium, these are I believe intended to be MISO lines to complement the SPI interface but could be used for any 3.3V digital logic.
  • Three outputs are connected to an RGB led (Or an external user added RGB led).
  • Reserved memory on the flash chip for non-volatile storage of an EEPROM backup and XeniumOS settings.
  • If you bridge the two recovery pins on power up, it will attempt to boot the XeniumOS recovery BIOS if available. This functions the same as a genuine Xenium modchip.
  • LFRAME abort mechanism (Ref Intel LPC Interface Spec Rev 1.1 Section 4.3.1.13) for a v1.6 console to prevent the Xyclops responding to the MCPX LPC Memory Read requests during boot (and conflicting with an external LPC memory peripheral). This is generally accepted to be better than shorting LFRAME the ground constantly which some traditional LPC memory addons do.

      Hey guys,
      So I was attempting to make my own OpenXenium modchips. I managed to get all the components and build 6 of them. Of the 6, 4 of them were successfully programmed with a BusPirate XSVF programmer (i figure I just need to reflow and check for bridges on the other 2). When I go to do the final programming using Ryzee's Xenium tools only 1 of the 4 that were programmed actually get detected with the software. Even then when I go to program that one chip with the the tools it only gets to 50% complete and then the xbox just freezes on the flashing process leaving the chip in a partially flashed state. Im using the recovery.bin file from xbins for flashing. I was wondering if you guys have any ideas as to what might be wrong in this situation. Im in the process of setting up an NXDK environment to see if I can build the tools .xbe from there.
       
      Thanks

      As above really, After trying a Pound HDMI converter and finding it lacking I was looking for a OG box component lead to get the most out of these little gems.
      But the only ones I can see on Ebay are the £5 jobies which may or may not be shielded but prob not....
      such as these:

      Does anyone know the jack size for the 6V 1A power adapter used for this thing? All the ebay sellers that have the power supply blur out the model number and overcharge.
