Continuing CyberSCSI saga...
« on: October 07, 2005, 01:36:16 PM »
I've just bought and installed a CyberSCSI for my CSMk2 and a SCSI HDD, it all appears to work except that if I remove my existing IDE HDD, I cant boot from just the SCSI. From past experience trying to install drives I supect I've missed something (possibly to do with RDBs, is there something apart from Install/Partition/Format? ISTR struggling to get an IDE drive recognised once). Here's what I've done and I would be grateful for any clues anyone can offer.
Thanks
Ian

Booting from my existing IDE disk, using OS3.9's HDToolbox I Installed the SCSI disk and Partitioned it. Next I formatted it then copied everything over to the SCSI disk. Next I set the boot priority of the first partition of the SCSI disk higher than the IDE and apparently I could boot from the SCSI disk. I could see both disks in the early startup menu and under workbench

However... Next I removed the IDE expecting to boot from just the SCSI disk and it wont boot - I just get the insert floppy screen. I rebooted into the early startup menu and the SCSI disk partitions aren't visible. However if I reconnect the IDE and reboot the SCSI disk is visible again.

I've even tried flashing the CSII ROM again just to make sure (thanks again for the manuals Brandon) but I still get the same results.

Does anyone know what I have to do so I dont have to keep an IDE disk hooked up? I'd like to have just the SCSI drive alone.

Another thing to add is that I'm using SFS - Is it possible that I only have SFS installed in the IDE HDD's RDB and thats enough for the SCSI HDD to work when the IDE is in?

I dont really understand how RDBs work and how to check/manipulate them  :roll:

Providing that SCSI termination has been set correctly to your chain, you must make sure that the system partition of the SCSI hard drive is set to bootable from HDToolBox.

I'd already done that. Provided the IDE disk is in I can boot from the SCSI disk by raising its boot priority to be higher than the IDE or by just selecting it in the early statup menu.

Everything is correctly terminated, the SCSI works fine when theres an IDE drive in the system.

Thats exact the explanation. The Kickstart ROM contains the FFS-Filesystem, so you can boot from any bootable FFS-Partititon without having to have the filesystem in the RDB of the Disk.
I assume you have the SFS-filesystem in the RDB of the IDE-disk so the Amiga is aware of it and can boot the SFS formated SCSI-Disk.
All you have to do is add the SFS filesystem to the RDB of the SCSI disk and you are set.
To do this open the HDToolbox select the SCSI-Disk, select partition and the click down right on add/update to add the SFS-filesystem. You should find the filesystem in the L drawer of your system partition.
After you have added the SFS filesyystem save the changes to the drive and exit HD-Toolbox. That`s it.
Not really interesting, but it`s there.

@inewhamn:

Follow the instructions for how to install sfs in the rdb from its documentation, but just do it on the scsi drive instead of the ide drive.

Also, if you dont have anything connected to the ide-bus, it will take ~9 sec for the computer to boot under 3.0 and ~30 sec under 3.1.

This software hack will disable the ide interface and thus remove that delay for each boot, but the first when powering on. This hardware hack will make the ide interface skip scanning and thus there will never be a delay.
