OS 3.9 Emergency boot disk

[Thomas]

I have followed the instructions on this page http://home.t-online.de/home/thomas-rapp/os39uae.html but it tries to make me boot from the cd rom with no emergency boot disk image, I just get to a cli prompt, no commands work because none are installed

Make sure you have the s/startup-sequence file in the right place. If you add directory C:\WinUAE\Workbench to WinUAE's hdd list, there must be C:\WinUAE\Workbench\s\startup-sequence as described on the page. Also make sure that startup-sequence has no extension (e.g. .txt). There is an option in Windows Explorer to hide known extensions. Disable this option to see and remove the extension. Or use the DOS command Rename.

so I try to boot off of my EMERGENCY BOOT IMAGE and I get a cache cdfs error, can not open "asim_atapi.device" unit 1, and then another requester asking me to insert AmigaOS3.9 in any drive.

Either change the EMERGENCY_CD file on your emergency disk to call uaescsi.device unit 0 instead of asim_atapi.device unit 1 or add your CD-ROM to WinUAE as a harddisk directory called AmigaOS3.9. The latter method might give you some problems (all files names in upper case, write protected files etc.)

Please ask again if you need further support.

Bye,
Thomas

It does not make any difference if you check "Add PC drives at startup" or not, because WinUAE no longer includes CD-ROM drives with this option. CD-ROM drives must either be added explicitly or by uaescsi.device emulation.

I get alot of AMIGAOS3.9 has read errors

As told before this is a MaxTransfer issue. A restriction of ASPI as Toni Wilen said.

Boot again with this startup-sequence thing and without the emergency disk in DF0. Then insert the emergency disk. Open a Shell window (in Emergency-Boot/System) and enter ed df0:devs/emergency_cd (I hope the editor works on this extemporized environment).

Now search the line that reads MaxTransfer = 0xffffffff and change it to MaxTransfer = 0xfc00

Then press Esc and enter X to save the changes. Enter Q instead of X to discard the changes.
