Tab5 PC 1.0.0

The first release of Tab5 PC: a 386/486 DOS PC on the M5Stack Tab5. See the README for the first start, copying files over Wi-Fi and the settings.

Firmware (one image, written at address 0x0, e.g. esptool --chip esp32p4 write-flash 0x0 tab5-pc-1.0.0-prev3.bin):

• tab5-pc-1.0.0-prev3.bin: for ESP32-P4 chips of revision v1.x (esptool prints "revision v1.x"). Tested.
• tab5-pc-1.0.0-postv3.bin: for revision v3.x. Built the same way, not yet tested on a device.

Licenses and source (the firmware contains third-party software, some of it under the LGPL):

• tab5-pc-1.0.0-NOTICES.txt: the notices and license texts of everything in the firmware.
• tab5-pc-1.0.0-source.tar.gz: the corresponding source (this repository at v1.0.0, tiny386 and ESP-Hosted as patched, SeaBIOS, the BIOS images, the Arduino core as built); SOURCE.txt inside explains how to rebuild.
• SHA256SUMS

No SD card images are provided: the Tab5 downloads FreeDOS itself, or tools/make_sdcard.py prepares a card. See CHANGELOG.md and docs/DISTRIBUTION.md.
