XIO 254 under DOS 2.5 tries to format MD and if the drive doesn'tsupport MD, it formats in SD, other DOS-Versions try only to format MD.
XIO 254 under MyDos works as following: If AUX1, Bit 7 is set, the disk is only cleared (empty directory written to disk). If AUX1 Bit 6-0 and AUX 2 are zero, the formatted disk will have the current density setting of the drive, if not, AUX1&AUX2 define the number of available sectors.
BeweDOS has no format commands in the FMS. The note and point commands deliver a relative file position rather than an absolute sector/byte position as the other DOS versions do.
You can use XIO 33 to delete (empty) MYDOS-directories.
MyDOS allows to ignore INIT- and RUN-addresses (in XIO39/40) by setting an appropriate AUX1-value (4=do Run & Init, 5=Run only, 6=Init only, 7=ignore Run and Init).
In XDOS this is possible via XIO 39, e.g. XIO 39,#1,0,0,"D1:LOA file"
XDOS allows the execution of every DUP command (DIR, LOA, SAV, COP,...) via XIO 39 and the density of a disk can be checked via XIO 34.

We need an update on this list for
