I today released a new EDR-DOS kernel version. This fixes a critical bug which could corrupt the file system if files with long file names were deleted.

This release also increases compatibility with MS SCANDISK and the DR-DOS TASKMGR.

New binary release 20240914 of the EDR-DOS kernel is out. This release fixes a few boot and compatibility problems with original IBM-PC and with disks larger than 502 GiB.

I today released a new version of the EDR-DOS kernel and command interpreter.

We made progress in preventing the EDR kernel from accessing uninitialized partitions.

This is an interesting one: DR-DOS shipped with a FDISK program which initialzed partitions with a file system right away, without the user having to FORMAT it. But because of this, the DR-DOS kernel never implemented proper filesystem validation.

The whole thing falls apart when using the EDR kernel with Free FDISK and NOT formatting a partition. Curiously, the kernel could then access the non-existing filesystem. But not anymore...
