Title: Cannot open "Scsi.device" unit 1
Post by: Bildheinze on April 16, 2008, 06:48:05 PM
Hy!
I always get that error message when i start up.

Don't know whats wrong..got oS3.5 and idefix,deleted the os cd driver

When i boot from the emergency disk,the cd rom is there...

-then after a warm reboot from my system the cd rom is still   there...

But when i cold reboot i get this error message and there is no cd rom drive..(when i hit "Find device "in idefix i can see the cd rom...but no chance to mount it....

is there something wrong with the startup-sequence???

Please Help!! :-?  :-?  :-?

The first thing I would check is that it is actually the slave on the first connector (which is what scsi.device unit 1 will always be) and not master or slave on the second (as you are using idefix I am guessing you have a buffered IDE interface), if so then the second connector is scsi.device 2 (master) and 3 (slave)

Also if you have the emergency disk for 3.5 copy its devs/dosdrivers over to your harddrives devs:dosdrivers and it should mount.

It's connected the right way,and i copied the driver from the emergency disk to the devs folder on my system..still doesn't work....this is weird...


booting up from emergency disk---cd rom there
warm reboot from system---cd rom there
cold reboot from system --cd rom NOT there..cannot open "scsi-device"unit 1

what i try now is give the cdrom an extra powerconnection,it is connected with the powersupply for the floppy disk...maybe theres a delay...

I usually get that when my CD drive is unplugged from the mains. Don't know if that's any use or good for any clues?

Hey Daniele,i tried another cd rom  unit and it's still the same....and Tokyoracer,thats interesting do you also then get another workbench message that your workbench is about to be resetet???

i'm glad i can still use it but always have to use that workaround first boot from emergency and the warmboot from system......

anybody  got another idea??

@Bildheinze

Have you disabled the SetPatch update? Have you installed boing bags?

It almost sounds like the drive isn't ready when the system first tries to mount it.  Maybe try using the wait command to put a delay in the bootup before it mounts the drive, eg:

wait 5
mount cd0 (or whatever is in your s/s)
...

@ merc
i tried that also with the wait till drives ready and put in up to 20 wait.

also when i do a soft boot from the system the cd rom is not there ..only if i boot before that from the emergency disk.

so i think it must be ready quick enough....

what else could it be...i tried 3 different cd rom drives now al the same..

OS3.5 updates (http://os.amigaworld.de/index.php?lang=en&page=18)

as far as i remember idefix uses atapi.device and not scsi.device. but i have a lot lot time to use it so i'm not sure enough. if atapi.device is in the emergency disk, and not at hard disk, copy it at the drawer Devs: and of course copy the emergency cd driver to Devs:DosDrivers

take a look at os3.5 faq (http://www.gregdonner.org/os35faq/installtips.html) it may help.

My guess is that the CD filesystem is on the emergency disk but not ond the system installed on the harddisk.

Look what is in L on your emergency disk and not in L on your harddisk and copy it over.

Just reinstalling IDEFix should do the trick as well.

Do you have the "idefix" or "loadide" command in your startup sequence?
It sounds as if you may not have.

As Lemmink suggested, I also suggest you re-install idefix after booting form your hard drive.

The problem is solved!!

Only with reinstalling idefix the problem was still there...but  a vesalia technician told me about doin a SKIPROMUPDATE in the start-sequence so i did that as it is written in this FAQ amije posted the link for.

http://www.gregdonner.org/os35faq/installtips.html#15

this skipromupdate is for switching of a new scsi-device it says. and reinstalled idefix after that..and now everything is working fine!!!

and again thanks everybody for the quick help,without this forum i probably would have given up by now!!! :-D  :-D
