Warm Start messages of all devices.
There is somewhere a list of "warm start messages" of all existing devices?
I know these:
1541:
73, CBM DOS 2.6 1541, 00, 00
1581:
73, COPYRIGHT CBM DOS V10 1581, 00, 00
vice emulator filesystem driver:
73, VICE FS DRIVER V2.0, 00, 00
Anyone can help with more messages from other devices and emulators?
For eg: jiffyDOS, CCS, Power64, IDE64... |

Help with more messages? What do you want to achieve with these? |

Nothing really complex, i'm trying to interact as accurately as possible with the sub-dirs in various formats, from 1581 (partitions) to emulators-filesystems-drivers.
But to do it i need to identify the actual device quite carefully, but not so carefully as if i were writing a irq-loader... so no low-level interaction required.
Only to send right command to device (for eg: "/0:" for 1581 or "cd:" for IDE64).
That's all.

Looks like you'll just have to find one of each device type to find out yourself :-)
Here's one I haven't seen before:

This one is a fairly common 1541 clone, most of them coming with original 1541 firmware, but there are a few weird ones, too. |

That's the wrong approach. Just try the command and see what happens, then remember and use the one which worked. Some drives e.g. CMD-FD accepts either "/0:" or "CD:" depending on the actual filesystem type. |

Thanks soci... this may be "the" solution...
Keep it simple!

Don't forget that for instance CMD HD has both partition and subdirectory support. Oh, and also if I remember correctly there's some bugs in the subdirectory handling of the 1581. I don't remember the specifics though. Might've been related to REL-files. |

To roughly detect drive types you can simply read the last 4 bytes of the drive ROM ($FFFC-$FFFF):
1541/1570/1571 will read the bytes $A0,$EA,$67,$FE.
1581 will read $24,$AF,$03,$FF
etc
Since these are the reset- and IRQ-vectors, they do not change on different DOS ROMs.

please explain. they are all the same in reality, but there is no reason for why they have to be, afaik. |
