IDE Autoboot patch for TOS 1.04, 1.06 and 1.62
Copyright (c) 2020-2021, Christian Zietz czietz@gmx.net
Find a ROM image of TOS 1.04, 1.06 or 1.62. Edit the following file:
- for TOS 1.04:
idepatch.fil - for TOS 1.06:
idepa106.fil - for TOS 1.62:
idepa162.fil
... in a text editor, entering the file name of the ROM image, selecting the TOS language (required only for TOS 1.04) and modifying the output format, if needed.
Then, depending on the TOS version run one of the following commands:
TOSPATCH.TTP idepatch.fil
TOSPATCH.TTP idepa106.fil
TOSPATCH.TTP idepa162.fil
... and you will get a patched TOS ROM image.
The code uses a short timeout for IDE devices, in order not to delay booting too much when no IDE device is connected. The timeout is more than sufficient for modern devices such as IDE/SD adapters, CF cards, IDE DOMs, etc. Booting from a mechanical harddisk, that takes tens of seconds to spin up, might only be possible after pressing the reset button.
For French TOS 1.04 users only: As the French translation takes up too much ROM space, the default DESKTOP.INF (that is only used when no DESKTOP.INF is found on the boot drive) is modified when applying the patch. The entries for floppy drive B: and virtual cartridge drive c: are removed. These icons can be added again manually, if needed.
