To check things on disks I usually just load my ClassicWB Lite 3.1 .HDF and insert the desired disk (and hope it's not NDOS)

Yeh.. Judging by the ROM residents in 2.x+ they were mainly looking to optimize startup times for floppy users. :-) Many startup-sequence related commands are in ROM.

back in time, with only an A500 it was no fun, and so it's today using emulators
for sure I would have bought a flash kickstart module to make some additions, if those thing were available in the old days |

You need extra RAM though. In your example you need 64KB+128KB+the size of the decompression routine. There are probably some tricks to reduce RAM, like using 1 buffer of 128K and decompressing 'backwards'. |

TO use ide0 as the hd controller in WinUAE is it just a case of disabling JIT and enabling A600/1200 IDE?

Some questions that will make me look very stupid but I'm too lazy to create a fake account to post them :-)
1) What's the need for "Version >NIL:" and "FailAt 21" at beginning of a stock Startup-Sequence ? 2) Which *%ç%* hardware really needs drivers to be loaded with BindDrivers ? Thanks in advance |

Thanks DamienD, my question wasn't maybe precise enough. Why did Commmodore/AmigaTech/Escom/whatever did put this one in their Workbench Startup-Sequence ? Were they expecting something failing with Error 20 ?

So with FailAt 21 it means that any error below 21 will not halt the whole startup-sequence, it will just fail at that line and go on. I don't think they did it to expect something failing, rather to make the startup-sequence work through even if something you add fails. http://wiki.amigaos.net/wiki/AmigaOS...ference#FAILAT >NIL: redirects anything the command outputs to the null device. This is so nothing is shown on a shell window. It's useful in the beginning of the startup-sequence, because it will not open a Shell window until there's some output. There could be tiny memory implications on this (opening a screen with a Shell window uses memory) but mostly, it will mean your boot will go almost directly to WB without showing a Shell window (unless other stuff throws output). It also cleans up the startup, otherwise everything would be verbose. |

"version >NIL:" does not much, if it is not followed by something like: "version >NIL: exec.library 45 20" this would test the version of exec and return 20 if it is too low, but be quiet if it is all right. if you put "FailAt 21" before that, the script would continue even with the error code 20 thrown. 2) E.g. the A2088 (XT) Bridgeboard needs BindDrivers |

I think the A2090 also uses BindDrivers, and the Oktapussy replacement firmware for Oktagon/Alfadata controllers can be loaded using BindDrivers.

And AFAIK the ROM driver is copied to ram in the same fashion as would a BindDrivers version file so you can make both version with a few build time switches. |

Version >NIL: might not look useful, but it does actually do something - it opens version.library and also sets two environmental variables with the version information of Kickstart and Workbench. Other parts of the startup sequence can then check Kickstart or Workbench versions without having to run the Version command again.
