1088XEL U1MB Firmware Released

Ten months after I started work on the custom U1MB firmware for the Mini-ATX 1088XEL, I’m happy to announce its public release. The 1088XEL – paired with the XEL-CF adapter – offers dual-CF card operation, as well as compatibility with SD/CF adapters and SD/IDE adapters. You can download the firmware, user guide and technical documentation from the 1088XEL Firmware Page.

Ultimate 1MB, Incognito and SIDE/SIDE2 Firmware Update

After some extensive development work following the previous update, the “final” firmware update for U1MB, Incognito and SIDE/SIDE2 is complete. New features include:

  • Dedicated High-Speed SIO menu
  • SIO2BT support (at up to 56kb/s) and high-speed SIO for PCLink and other serial devices
  • Built-in CIO “Z:” RTC device handler
  • Improved SDX support
  • Rapidus plug-in and support for PBI BIOS extensions in fast linear 65C816 RAM (U1MB only)
  • General SIDE loader improvements

Ultimate 1MB, Incognito and SIDE BIOS/Loader Update

New updates for Ultimate 1MB, Incognito and SIDE/SIDE2 may be found in the firmware section of the site. New features include:

  • Loader: joystick operation augmented by console key home, page down and page up navigation keys (primarily aimed at XEGS with keyboard disconnected)
  • Loader: joystick control generally improved with proper debounce and better auto-repeat
  • Loader: position in file or option list now preserved when moving between menus
  • Loader: minor bug fixes
  • Main BIOS: config changes requiring reboot now detected when swapping profiles
  • Main BIOS: dual-level HDD write lock (see below)
  • PBI BIOS: SIO2BT automatically handled by high speed SIO handler (simply enable HSIO for the appropriate drive)
