On this card there are also jumpers for SCSI IDs, there are 3 jumpers J10, J11 and J12. The manual explains only the position of the jumpers for the RAM, but not that for the SCSI IDs. Do you to know the settings of these jumpers?

Thanks

At a guess they'll be the SCSI address. Those are usually 3 bit addresses.

Please keep it in English!

SCSI address setting is a rather large user land subject. My guess is you are setting the controller ID there and unless you know what you are doing leave it alone as you found it. The controller is usually ID7 so all jumpers set.

But I don't have 7 devices attached and I wouldn't want to wait for the system to check if all are present. This slows me down the boot.

It doesnt usually matter. The controller will scan all devices unless you ask it not to in software. I dont think this setting does what you think it does. Its there for when you have 2 controllers on a SCSI chain. Leave it alone.

Applications where you have multiple controllers on a chain include IP over SCSI etc.

And it doesn't (or shouldn't) take long to scan the chain anyway. It should take a matter of seconds.

1 minute and 36 seconds pass from when I turn on the computer until the WB screen appears. They seem a little too many. I noticed that during the boot there are some initial stall phases with the hard disk LED that seems to be on steady, then after a minute it flashes and loads the WB even if the floppy click has already been heard for at least 30 seconds.

Which kickstart? That is a known issue in KS3.0 i think? 1 min 36 seconds is the known time some drivers will wait for all disks to spin up.

The kickstart is 3.1, but it seems slow to me. 1 minute and 36 seconds is too long. I also have an A1200 and A4000 with the same kickstart and they don't take long to boot ..
