SCSI HD Bootup/mounting problem (possibly SFS related?)
« on: June 02, 2007, 09:23:46 PM »
recently i made the decision to switch from IDE to SCSI. i currently have a 8GB SCSI HD and use the SCSI interface on the CSMK3. After testing to see whether my SCSI HD and SCSI setup in general works using FFS (SCSI termination, read/write), i decided to switch to SFS. i remember last time have a hard time setting up this bugger. Anyway, after going through the trouble of getting SFS even recognised properly as a Custom File System, i finally got it recognised as SFS\00. here is the settings i used (for reference):

Indentifier: 0x53465300
Mask: 0x7FFFFFFE
MaxTransfer: 0x7FFFFFFF
Block Size: 512

I am guessing these settings are correct, as everything else i put before this, the file system got recognised as CFS\00!!! Now i have 2 spare IDE hard drives that i use, 1 with OS3.5 and one with OS3.9 (my main backup). now, i think it's worth mentioning here that when i formatted (quick format) the SCSI HD with FFS, this HD only got mounted (on the desktop) with the IDE HD with OS3.9 on. But when i formatted (also quick format) the SCSI HD with SFS, it only gets mounted with the IDE HD with OS3.5 on. But on both IDE HD, the SCSI HD gets recognised using HDToolbox (and the Phase 5 SCSI HDToolbox). i carried on despite this (i haven't yet made the SCSI HD bootable). Using the OS3.5 HD as the bootup HD, i used this HD to install OS3.9 onto the empty SCSI HD and also i copied over the latest 68060 library files (if thats worth noting). Now i used that checkpoint to make the SCSI HD bootable on it's own and see if it works so far without the use of any IDE HD. So i fired it up (fingers crossed!) and........ DAMN!  I knew it was too good to be true! The SCSI HD refuses to bootup!!! The HD seems to get accessed, but after the reboot, the machine seems to freeze: No Amiga output from the Picasso IV and also i get the flashing green Amiga LED (an error). so when i try again with a reset, or if i switch off the machine and switch back on, i am presented with the red "Software Failure" screen. I haven't much clue as to what is wrong with the SCSI HD. I am guessing there is something on there that is upsetting things. i am not 100% sure is this is an incorrect SFS setup or whether SFS is incompatible with a 4GB+ SCSI HD. anyone got any clues cos i am banging my head against a brock wall here! Here is a quick diagram of the SCSI termination setup:

ultra-2 lvd/se terminator
][
csmk3 scsi port
][
8gb scsi hd
][
ultra-320 lvd/se terminator

others notes i should make. I made an emergancy disk and tried to bootup with this, but i couldn't (it asked for scsi.device i think). I use 68pin SCSI cable but i am not sure about SCSI Termination power. it's worth noting that this SCSI HD seemed to work perfectly with FFS.

Hi,

I think I had to turn SCSI Term to off on all my HDs for my SCSI chain to work properly (at one point it had 4 SCSI HDs, 1 SCSI CDRW and a Scanner). Can't remeber the exact reason but I set my SCSI chain up after reading up about SCSI on the net. And it's been in use for around 5 years now with no problems (well apart from when I forgot to reconnect the scanner (which provides termination) - oops).

Here's a good link for checking if your SCSI chain's set up right: http://www.scsita.org/aboutscsi/SCSI_Termination_Tutorial.html

Apart from that make sure your boot partition is smaller than 2Gb. The rest can be one big partition. I have a 340Mb boot partition and two 55Gb partitions on an IDE HD hooked up to my SCSI chain via a IDE-SCSI adapter. Works out a lot cheaper/Mb than pure SCSI HDs.
