### AI overview

frank-xt8086 firmware lets the RP2350B on the xt8086 board provide chipset support for a real Intel 8086 or NEC V20. The excerpt says to flash frank-xt8086-1.00.uf2 with a Debug Probe or use BOOTSEL/reset and copy the file to the detected drive; floppy and hard disk images belong in /XT/ on a FAT32 microSD card. DEL opens SETUP at startup, while Win+F11 opens the drive menu and Win+F12 opens SETUP during operation. This build lacks a serial console because GP44 carries the board's right audio channel; enabling UART_CONSOLE=ON restores the console but makes audio mono. The code is GPL-3.0-or-later.

### Source excerpt

rh1tech (Mikhail Matveev) has published the first release of frank-xt8086 on GitHub. It's firmware for the xt8086 board, where a Raspberry Pi RP2350B microcontroller acts as the whole chipset around a real Intel 8086 or NEC V20 processor. That means the RP2350B handles the support hardware an early PC needed, while the original CPU does [...]
