Taito TypeX4: Playing around with the Built-in BIOS Developer Mode

This is something interesting I found while playing around with my Taito TypeX4. Normally, TypeX series arcade base units do not allow booting from USB/LAN or even show the Boot Menu.

However, if you’re like me and like to play around with settings that you shouldn’t, then if you have your hands on a TypeX4 that’s been decommissioned from overseas you can enable a “Developer Mode” which allows you boot from USB, LAN and other boot options.  To enable Developer Mode, you need to access the BIOS Setup Menu which is password protected. I’m not giving out any BIOS passwords since the TypeX4 is still in service, so don’t ask for it. Wait until I have a guide on recovering passwords from motherboards in general finalized.This allows you to actually boot your own Windows/Linux installation on your TypeX4. Hardware-wise, it has some very solid all-round specifications that can make it a very nice desktop PC.

So if you happen to come across one and manage to get into the BIOS, consider enabling Developer Mode to re-purpose some arcade hardware and give it a new life than being scrapped or tossed into land fill. Here’s my unit booted into Ventoy, a god-tier USB ISO loader for BIOS/UEFI systems just for fun.Until next time though… stay safe. 😃
