Finding what one is looking for on the Xbins FTP server can be a daunting task. There are so many files for many different consoles and stored under many different subfolders. XBOX in this case is the xbins FTP server folder for all things ogXbox related. For the most part, the subfolders there break down the content as to where it will reside: - Console Based Applications for content that will run on the Xbox - PC Based Applications for support tools that run on a PC. There are a few other subfolders for Xbox tools; however, these two contain most of what modders seek. In Console Based Applications, modified and original Xbox BIOSes are found in the subfolders of the bios folder. Look in the developer's or BIOS named subfolder for the latest MULTI_VERSION BIOS (at least Xecuter and Evolution-X have a MULTI_VERSION subfolders, not all do). Make sure you get a BIOS that works on your console version. There are v1.0-1.4 and v1.6 compatible BIOSes. And, not all devs released a BIOS that will work on v1.6 consoles. For a v1.6 console, until recently with the release of CerBIOS, Evox M8plus (256KB BIOS) and Xecuter X2 5035 (512KB BIOS) not suitable to be used with all modchips were your only choices. NOTE: Aladdin and cheapmod designs only have 1 256KB BIOS bank. Limiting you to EvoX's M8plus_16.bin BIOS.

It is available from Xbins FTP server. Use Team Resurgent's Pandora v1.0.7 Windows application to connect to and download it. Download the Pandora v1.0.7 release from GitHub - Team-Resurgent/Pandora You'll find the file at XBOX/Console Based Applications/apps/emulators/x86/dosxbox/dosxbox_v13.zip Or, download it from this xbins FTP server mirroring web site: https://xbxbx.ams1.ppn.prutzel.com/xbins_xbox_mirror/Console Based Applications/apps/emulators/x86/dosxbox/dosxbox_v13.zip

FlashBIOS is Team Xecuter's MS code free BIOS for their X2 or X3 modchips. It is used to reflash a modified Xbox BIOS to them so you can do actual Xbox operations - play games. FlashBIOS may or may not work with other modchips to flash a BIOS to them. IIRC, FlashBIOS has a very limited list (2) of flash memory chips that it can reflash.

Evoxdash's Flash BIOS option.

The X3 BIOS does not contain a replacement dashboard. If you get it to run an old version of XBMC, it is installed on the hard drive. Missing F and G partitions is caused by not having the Use Saved Partition Table set to Enabled.

With the X3 BIOS and a 2TB hard drive, you must Enable the Use Saved Partition Table option in the BIOS's configuration settings. X3 Config Live Menu Options Disk Tools > New Hard Drive Upgrade > Use Save Partition Table = Enabled/Disabled (Press A to toggle the value.) Press B to back out of the submenu items. Next, verify that the replacement dashboard's XBE file is in the boot order list to be loaded on startup. X3 Config Live Main Menu > Customize X3 BIOS > Dashboard Filenames and Dashboard Boot Drive = <Xbox Drive Letter where located>. IIRC, the X3 BIOS does not look in subfolders for the listed Dashboard Filenames. It only looks in the set boot drive's top-level/root directory.

The IDE-to-SATA bridge on the Startech adapter is a Marvell 88SA8052 chip. You should not have slow boot times with the Startech adapter. Try a different 80-wire 40-pin high-speed IDE cable.

XBPartitioner v1.3. What's effed up with the partitions? Don't do anything other than take a picture of its main screen and post it in a reply. To exit the app, press Back followed by any button other than Start.

Correct, the hardware has already been initialized by the stock BIOS, UDMA2. A BFM BIOS does not do any hardware initialization. It only replaces the Xbox's kernel/OS that is running from RAM.

Make sure all of the IDE connectors are fully seated in all of the devices: motherboard, DVD drive and hard drive. Verify that the hard drive is being powered with the correct voltages by the power supply. With a multimeter, measure the voltage level between the Yellow and black and red and black wires of its Molex power connector. What values do they read? Is it an IDE hard drive or a SATA hard drive with an IDE-to-SATA adapter? What brand and model of hard drives?

Don't throw it away. Someone will be interested in buying it from you for parts. Is it a v1.6 motherboard and PSU transplanted into a v1.0-1.4 case? That will short out the transister Q7C2 by the Xyclops chip since there's another mounting support and grounding tab under the motherboard that touches it between the GPU and encoder chip. A v1.6 case does not have that mounting post/grounding tab present. If so, the grounding tab needs to be bent down so it does not touch the motherboard.

Don't throw it out. Fix it! What video output mode is set: NTSC or PAL? Does your TV set support that mode? I know when I change my NTSC Xbox to PAL and connect it to my TV set, the screen is scrolling rapidly and the output is in black and white. Is your Xbox modded? If so how, soft or hard mod? Softmodded, which softmod package was used? Hardmodded, which modchip and BIOS are installed? Some modchips have button combos that change the video output mode from to PAL or NTSC by pressing them.

Did you install a new larger hard drive - SATA hard drive with an IDE-to-SATA adapter? If so, did you swap out the stock 40-wire 40-pin IDE cable for a new high-speed 80-wire 40-pin one? If not, do so to fix error 13. Is the BT pad on the Aladdin modchip directly connected to ground or does it have a wire running towards the front panel connector to tap off of the power button signal? If the latter, a short tap of the power button should boot into the stock dashboard. Modchip disabled. A long power button press enables the modchip to boot the BIOS stored on it which loads, if installed, a replacement dashboard. XBMC in your case.

They are the parallel Address and Data lines that run to the TSOP/OWNmod ROM to load the BIOS into the CPU to run the machine language code stored on the chip.

That's a old so called 29-wire, more than 29 connections to the motherboard, OWNMod design. There are more than 29 wires - 32 I believe. But 29 are signal lines, address and data bus, the others are power and ground. It uses a 256KB EPROM or FlashROM to hold a modified Xbox BIOS. See: https://web.archive.org/web/20151009063717/http://www.xbox-scene.com/modchips/ownmod_diagrams.html Edit: It can easily be removed if you have experience soldering. Desolder all 29+ wires that connect to pads on the motherboard. I would leave all of the wires soldered to the EPROM/FlashROM.. Edit: Where do the wires from the switch connect to?

How's your console modded? If softmodded with Rocky5's Xbox Softmodding Tool, Rocky5 released a new version v1.2.0 that mentions fixing a PAL-60 issue. Doiwnload, extract and upload the Installer Variants / Quick Update.zip from the Build 1.2.0 pre-built repository. Then run it to update to the latest softmod release.

Where is this repo located?

No.

It does still look like a simple PLCC32-to-DIP32 adapter. Nothing fancy or special about it. Edit: However, as @Bgsmods59mentions, he had problems with his adapter like the OP's. There may be some bad solder connections between the PLCC32 socket and the adapter PCB.

Ok, I don't have an XGecu programmer. I was not sure which PLCC32-DIP adapter they provide/use.

Hmm, did you buy the adapter from XGecu with the programmer or later from somewhere else. I don't know if XGecu's adapter is a simple PLCC32 to DIP32 adapter. From the programming software screenshot, it looks like it is.

For the Xgpro software, press the ID Check icon. The device's type should be displayed. It may be an SST49LF020A instead of SST49LF020.

When in the Xbox, what software did you try to use to reflash the chip? What was the error it displayed? Try Evoxdash's Flash BIOS menu option. It will display the device's Manufacturer and Product ID values.

Check the voltage level between pins 2 (+ probe) and 3 (- probe) or 2 (+ probe) and 1 (- probe) of the the PWM fan speed controller. The FANPWM control signal is an output of the PIC processor (System Management Controller) at pin #13. It is a digital signal. To view it, use an oscilloscope or logic analyzer.
