The problem was that these routines ececute from bank 4, but when the disk error hooks take control they expect bank 0 to be active.
The LUN_INFO function can now return a new flag that when set will cause Nextor to ignore the device+LUN combination when searching for suitable devices to perform automapping.
- Fix: after booting pressing 3, CALL SYSTEM doesn't work. - Fix (hopefully): slot disable keys not working on real machines.
Also, NEXBOOT tool now accepts "*" parameter, to disable all Nextor kernels in the next boot.
…edia change if the driver provides drive mapping via DRV_CONFIG.
…ut has the "ignore for automapping" flag.
When using 7BB0h there's only room for 16 bytes, but the DPB is 19 bytes, thus an incorrect one was being used.

Fix: broken RAM disk (introduced in RC1).
Fix: disk errors for old MSX-DOS 1 file functions in BASIC crash the computer (Call to BDOS from the DOS2 driver ends nowehere #59).
Add: new flag returned by LUN_INFO allows to instruct Nextor to ignore devices when searching devices for automatic device to drive mapping (Impossible to implement phantom drive properly #54).
Fix: files can't have 3 or 4 in their names in DOS 1 mode (In DOS1 mode files with certain extensions can't be found/loaded #55).
Fix: after booting directly yo BASIC by pressing 3, CALL SYSTEM doesn't work.
Fix: slot disable keys don't work on real MSX computers (Slot keys do not work? #49).
Add: new boot key, pressing
Nat boot time disables all the Nextor kernels present.Add: default DPB gets a fixed address of 7BAAh in banks 0 and 3, so it can be customized reliably.
Add:
PROMPTroutine made available to drivers at address 41E8h (Implementing phantom floppy drive in device-based subsystem #42).Fix: the DOS 1 variables "data buffer changed" and "redirect console output to printer" were not zeroed when switching to DOS 1 mode at boot time.
Fix: can't change volume name when there are long filename entries in the root directory (Cannot change volume name by command VOL - System file exists #57).
Fix: absolute sector read/write functions not working properly when a file is mounted to a drive (Nextor shouldn't block sector I/O to MAPDRV drives when FAT12 disk images are used #43).
Fix: bad sector buffer management when writing to a mounted file causing data corruption on the mounted file (_MAPDRV mount disk image - buffers from RAM on write not save to disk. #58).
Fix: drive parameters not updated on first access to a drive after a media change if the driver provides drive mapping via DRV_CONFIG, causing bad data read (Device-based removable media replacement problem #45).
