EDR-DOS kernel r20240914

This is a snapshot release of the single-file (KERNEL.SYS) and dual-file kernel (DRBIO.SYS, DRDOS.SYS) flavors as well as COMMAND.COM. 1.44M floppy images are also provided.

If unsure, which flavor to use: the single-file version is probably the one you want. You may consider the dual-file version for maximum compatibility with an existing DR-DOS installation.

Changes to release 20240821

• fix kernel crashes (division error) on systems with FAT partitions beyond 502GiB into the disk
• fix kernel not booting on original IBM-PC due to INT 3 vector not being properly initialized
• fix kernel not being able to boot from second disk if first disk is empty
• fix the dual-file kernel not finding DRDOS.SYS when booting from B:
• expand COMSPEC to absolute path
• for additional changes see the Changelog: r20240821...v20240914
