Title: NoNCRScsi from Luciferin distribution
Post by: tnt23 on February 08, 2009, 06:23:42 PM

In Luciferin distribution, there's a module called NoNCRScsi. I wonder if it can be used to inhibit SCSI drives search on A3000 if there are no SCSI drives in the system?

I don't think so.  A3000 has WD SCSI, not NCR (like A4091, A4000T).

Any chance of disabling 3000's WD controller then? Something like NoIDE, but for SCSI.
Or perhaps one could assemble a custom KS without SCSI module(s)?

Since NoIDE disables scsi.device maybe it's possible to use it.

NoIDE replaces the scsi.device by a dummy RomTag that does nothing. Effectively disables the IDE controller. This can be handy, if you don't have any drives at the IDE port and want to avoid the delay for the driver to find that out.

Both is possible. I'm not sure how the RomTag is called for the A3000 SCSI device, but if it's just "scsi.device", you could hack the right name into the NoIDE or NoNCRScsi RomTag and use that (I'm not at my machine right now, so I can't check the actual names of the romtags used). I too had a KickRom without IDE module on my A4000 machine.

If scsi.device is the problem then why not just delete it?

I have Buddha controller in my system, seen by 2nd.scsi.device. If I get rid of scsi.device, will I still be able to access devices on Buddha?

Thing is, I've never had any experience with putting KS in flash.

So I was brave enough to throw NoIDE into Deneb's flash. Whoa! Gone are scsi.device and long boot delay. Buddha is still here with its 2nd.scsi.device.

Thanks all!

Nice.

BTW: You don't have to be brave just to try it out. No need to flash it into the Deneb -- PsdLoadModule will work just fine for that purpose ;)

If you are building your own ROM then you should get this...

http://aminet.net/search?query=SCSI4345p

This patches some bugs in the SCSI and IDE devices but also has versions that disable the devices during bootup (faster). The funny thing is that Chris Hodges is the first author listed in the readme. Hi Chris! You do need AmigaOS 3.9 BB2 though. The device can also be left out of the ROM with no problems if you don't want it at all.

If building your own ROMs I would also recommend...

I should have known that, since I've read through the Luciferin docs! :)

Thanks Matthey,

Definitely will check these links. While I am sticking with 3.1 for now, I might want to look at 3.9 some day.
