- Big-DOS is freeware. For details and the content of this package refer to
- bigdos.txt!
-
-
- Big-DOS is an ISO 9293 filesystem that replaces the GEMDOS of TOS (not MagiC!).
- It works with up to 32 MS-DOS partitions with 512-byte sectors up to 2 Gbyte.
- That means also MS-DOS partitions greater than 32 Mbyte with more than 65535
- sectors. The count of sektors per cluster, as since GEMDOS 0.15 in TOS 1.04),
- doesn't matter. With the ACSI and IDE interface only 1 Mbyte harddiscs can be
- accessed.
-
- Big-DOS tries to lock a removeble cartridge using XHDI.
-
- DOSMODE.TOS shows and alter the legal characters for filenames on each drive:
- GEMDOS: A..Z0..9!#$%&'()-@^_`{}~"+,;<=>[]| and capital umlaute
- ISO: A..Z0..9_
- MS-DOS: A..Z0..9!#$%&'()-@^_`{}~ and capital umlaute
- If a program try to create a file or directory with an illegal character, it
- gets EACCDN (-36).
-
- To install Big-DOS, put it before Meta-DOS and MiNT in your AUTO folder. For
- MS-DOS partitions of more than 32 Mbyte, you also need a harddisc driver which
- can handle MS-DOS partitions type 6 and allows access to more than 65535
- sectors via Rwabs(). Big-DOS tries to change the XHDI DOS limits.
-
- For Atari's AHDI 6.061 a binary diff is included (you need `Binary Patch' from
- Robert Federle). AHDI.PRG and BINPATCH.TTP should be in the directory of
- Big-DOS. Then start BINPATCH.TTP with the parameter `ahdi6061.bdf'. If you
- dont boot with AHDI, you can copy AHDIBIGD.PRG to your AUTO-Folder for
- testing. If you boot AHDI, you have to rename SHDRIVER.SYS on your boot
- partition and then copy AHDIBIGD.PRG to the root directory and rename it to
- SHDRIVER.SYS. If you dont use Big-DOS further, you have to remove the patched
- AHDI, to avoid that too big partitions were offered to TOS! You have been
- warned!
-
-
- Application, which manipulate the memory management using undocumented
- variables, won't work.
-
- There are several Programs that initialize the filesystem not correct. By the
- first access or after a media change, an error message is printed on the
- screen. If you type J or Y for yes the correct value will be written on disc.
- Contact the responsible programmer and tell him about the bug.
-
- BigDOS: FAT start of A: shall be »media«, $FF, $FF [$FF]! Write? [JYN]
- BigDOS: Media byte in FAT of A: is $00, shall be $00! Write? [JYN]
- BigDOS: Media byte in boot sector of A: is $00, shall be $00! Write? [JYN]

-
- XHDITEST.TTP shows for a given drive letter the partition size, the XHDI
- version of the harddisc driver and tests the DOS-limits function.

- :-/ available, but could not change the limits
- :-) available and could change the limits
