I noticed that at least @ecm-pushbx s EDR-DOS and Calderas OpenDOS kernel 7.03 accept an unformatted partition created by Free and MS FDISK as valid FAT-16 volume. My first guess...
This is more work than I have thought, because I have yet to find a way to keep the unneeded SvarLANG strings out when not building the UI.
Windows 95/98 prevent FDISK from writing to partition table back to disk. Lock drive to make FDISK work under Win95+.
The I16-GCC makefile does currently not have correct dependency information for the targets. Especially if a header file gets updated, the targets depending on it do not get rebuilt. It...
Currently there is an incompatibility between the drive letter assignment of the (E)DR-DOS kernel and FDISK, as FDISK follows the FreeDOS (and Microsoft) way of assigning drive letters to partitions....
MS-DOS syncs the BPB volume label to the volume file if such one is created. EDR currently does not do this. https://github.com/microsoft/MS-DOS/blob/2d04cacc5322951f187bb17e017c12920ac8ebe2/v4.0/src/DOS/CREATE.ASM#L224
Currently the kernel is zero-compressed. The single-file kernel is ~60K in size. It could be made smaller by utilizing another compression algorithm. Constraints: uncompressor should fit within 512 bytes.
The following are the DPBs of an uninitialized FAT-32 partition (boot sector filled with 0xF6). MS-DOS blocks access, ~~the EDR kernel not~~ the EDR kernel also blocks access since commit...
At least Digital Research DR DOS 6 and Caldera DR-DOS 7.03 kernel files are named IBMBIO.COM and IBMDOS.COM. As the dual-file builds purpose is mainly being a drop-in replacement for...
When running DR-DOS 7.03 MEM.EXE while booted under EDR-DOS kernel, two issues arise: 1. MEM shows an impossible memory size for the DOS 2. MEM cannot peek into high memory...
