v2.1.0 beta 2

NOTES:

  • The .SunriseIDE.ROM version won't recognize the master device on emulators. Use it with real hardware for better compatibility, use .SunriseIDE.emulators.ROM version with emulators.

  • The old EMUFILE.COM tool doesn't work with the new emulation modes introduced in this version. Make sure to use the newer version, included in tools.zip in this release.

  • If you are a driver developer please take note of the BREAKING CHANGE at the end of the changelog below.

Changelog:

  • Nextor will now try to load MSXDOS2.SYS if NEXTOR.SYS is not found in the boot drive.

  • The method for selecting partitions for automatic mapping has changed from requiring a NEXTOR.DAT file in the root directory to having the "active" flag set in the partition table.

  • Now the first 9 partitions of a device will be scanned during the automatic mapping procedure, this includes extended partitions.

  • FDISK allows to change the "active" flag of new and existing partitions.

  • FDISK now always creates extended partitions, even if 4 or less partitions are defined.

  • FDISK now creates FAT16 partitions with a partition type code of 14 (FAT16 LBA) instead of 6 (FAT16 CHS).

  • The numeric keyboard can now be used both when booting and when changing disks in disk emulation mode.

  • Russian keyboard is now properly recognized (numeric keys only).

  • Introduced the boot key inverters.

  • Introduced the one-time boot keys.

  • Introduced the NEXBOOT.COM tool to set the RAM based one-time boot keys.

  • Introduced the RAM based one-time disk emulation mode.

  • The method to enter the old disk emulation mode (now named "persistent") has changed from requiring a NEXT_DSK.DAT file in the root directory to storing a pointer to the emulation data file in the partition table of the device.

  • Pressing the 0 key at boot time will delete the pointer to the emulation data file in the partition table, thus permanently disabling the emulation mode - no need to manually do anything else.

  • When Nextor is waiting for a disk key press after having pressed GRAPH in disk emulation mode, now you can press GRAPH again to cancel the disk change.

  • The first Nextor kernel to boot now clears the screen before invoking the driver initialization.

  • ARG is no longer used as temporary work area by the Nextor kernel, this should improve the compatibility of games in disk emulation mode.

  • Fix: drive was remapped in case of error (even if it was retried successfully).

  • Fix: boot sector checksum calculation had a bug that caused "Wrong disk" errors.

  • Fix: #1 pressing CTRL+STOP while Nextor was trying to load NEXTOR.SYS hanged the computer.

  • Fix: #23 computer hanged when booting with one single drive letter (e.g. when using single-device controller in a computer without internal disk drive).

  • Fix: #29 wrong stack management hangedd the computer when a file handle was read or written to a number of times.

  • Fix: computer crashing when more than one Nextor kernel was present as soon as the extended BIOS hook was called (for example, when loading COMMAND2.COM).

  • Fix: there was Nextor kernel code in the 1K free area in pages 0 and 3, so putting anything here caused problems, e.g. DOS 1 mode didn't work.

  • _GPART now returns the status byte of the partition, and allows to retrieve the device sector number that holds the partition table entry instead of information about the partition.

  • BREAKING CHANGE for driver developers: the address of CODE_ADD, used by the CALLB0 routine, has changed to F1D0h (it was F84Ch).

v2.1.0-beta1

  • All the changes and fixes of v2.0.5 beta 1, including the addition of the license file and the Markdown documentation.

  • Fix #3: RDBLK can't read files with read-only attribute

  • Change in boot keys: now the key to request one single drive per driver is the 5 key, and CTRL is simply passed to MSX-DOS kernels as when booting with MSX-DOS.

  • Added the "User is requesting reduced drive count" flag to the input of the DRV_INIT routine and the DRV_CONFIG routine.

  • MegaFlashROM SCC+ SD kernel is now offered in two variants, for 1 slot devices and for 2 slots devices; the difference is the number of drives allocated at boot time.

v2.0.5-beta1

  • Fix: if an error occurred while performing sector access and the user selected "retry", the higher byte of sector number was being reset to 0. Thus, when accessing past the first 32MB of the device this caused weird errors, and data corruption when writing.

  • Fix: FDISK crashing when the system booted directly in BASIC.

  • Fix: the Nextor kernel code was writing to the driver space in ROM, causing crashes due to inadvertent ROM bank changes.

  • Partitions of type 14 (FAT16 with LBA mapping) are now recognized as a valid FAT16 partition at boot time, and displayed as "FAT16" in partition lists in fdisk.

  • MBR signature (0x55AA at the end of the sector) is now added to the MBR of the generated partitions by FDISK (previosly it was being added to the sector with the partition table only).

  • Drivers can now specify the desired number of drives and device to drive assignment at boot time via the new DRV_CONFIG routine.

  • FDISK now uses its own implementation of printf and does not depend on the C standard library.

  • Add license file

  • Add documentation as Markdown files
