Hello Carsten, >> INT 2F CU - DOS 5+ - FLOPPY-DISK LOGICAL DRIVE CHANGE NOTIFICATION >> AX = 4A00h ... >> Return: CX = FFFFh to skip "Insert diskette for drive X:" message
> this helps for new applications or applications where we have the > source, but it does not help with all the existing applications Given that this API has been there for ages, those existing applications just have a very long-lived bug by failing to use the API. However, you could write a tiny TSR which will hook int 2f and suppress the disk change message, or show it in a way which is compatible to full screen TUI and GUI apps. In situations where it is unable to show the message, this TSR could set appropriate flags to mark B: as not inserted, or take similar measures to make access to DJ-style B: fail. I really do not think that this is a job for the kernel itself. It has been ages since I DELIBERATELY used the DJ mechanism at all. Normally I just access files on A: and very few apps would insist on using B: for things unless you explicitly tell them. So a feature to block the mechanism from ACCIDENTALLY triggering would be needed even less often than that and a TSR is enough :-) Regards, Eric PS: FreeDOS does not include a DRIVER.SYS driver, or feature. That was a very ancient MS DOS feature which let you override BIOS based detection of floppy drives and their geometry, see http://info.wsisiz.edu.pl/~bse26236/batutil/help/DRIVER_S.HTM Maybe we COULD add a config.sys command instead of a device=... driver, but I do not know any hardware needing it? Basically, it tells DOS a BIOS disk drive with any given CHS geometry exists. _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
