Jafar Chip

The "Jafar Chip" is a dual 512kb bank chip with Manual (switch) controlled bank selection. It comes pre-flashed with Xblast on both banks and It's recommended to never flash bank 2 so as to maintain access to Xblast OS from the chip whenever it's needed. This version of the chip only see's 512kb at any given time.

What's included

Why Choose The Jafar Chip Over The Classic Aladdin Chip

• The Jafar chip is a reworked version of the well known "Aladdin XT+4032 XT PLUS2" chip for the OG Xbox with upgrades in both memory and PCB design.
  
• Jafar has 4 times the flash memory space. Instead of Aladdin's 256kb memory chip, the Jafar has a full 1mb of memory.
• The Aladdin has bugs in the original board that are worked out in the Jafar. Aladdin uses the 5v pin to power the LED which is fine for 1.0-1.4 because its 5v pin is switched, but on 1.6 the 5v pin is NOT switched. On a 1.6, If the Aladdin is installed incorrectly the LED does not turn off when you power your Xbox console off. If you install an Aladdin correctly on 1.6, you have to remove the 5v pin and wire switched 5v in from a different location on the motherboard. Jafar works with the 3.3v pin, which is switched in all Xbox revisions, so you don't have to wire switched 5v in from another location on 1.6. The Jafar's LED turns off when you power off your console on ALL motherboards.
• The (gen3) Jafar is a "No Wire" mod-chip. The only wire you need to solder during the install is on 1.0-1.4 between the D0 pad and ground. 1.6 has always been harder to chip due to missing traces on the board but the D0 equivalent on 1.6 (called L-Frame) still needs to be grounded. This is what tells the motehrboard to boot bios from the LPC port rather than the on board bios location. 1.6 LPC Rebuild QSB's are available or I've provided a wiring diagram to rebuild it by wire. There is nothing on the Gen3 chip that needs to be soldered.
  
• Modern batches of Aladdin chips are coming from suppliers with counterfeit SST memory chips that can't be flashed in an Xbox console. You have to purchase a programmer to flash these chips with a PC. Both versions of the Jafar chip can be flashed in the Xbox console.

Xblast works on all motherboard revisions. With Xblast OS you can backup your EEPROM, Format a Hard drive, and flash bios over network, from HDD, or from Cd/Dvd rom. It also has a very nice feature of being able to test 128mb ram installs. When you're running Xblast you're able to install one RAM chip at a time and the console will still boot for testing. This is not the case with other mod chips. Having a chip with Xblast on hand for 128mb ram installs is quite nice if you're going to be doing multiple installs. It can be a very helpful shop tool for a technician as well as a good hard mod method for a player.
