A4000 freeze, what SCSI settings do you have in CSPPC for an ACARD 7720UW device?

[keropi]

I was wondering what settings to use, right now all is set to auto, but it does not feel too fast, plus doing a SYSINFO DH0 speedtest, it gives 6.5MB/sec... doing a second leads to a reboot...
I have connected to the Acard 7720UW an 80GB WesternDigital IDE drive , acard had termination disabled and I use 2 LVD/SE terminators....
below is a pic, with the CSPPC settings and the different that UNITCONTROL shows... ?  also SCSICONFIG complains that the  Cyclinder*Heads*Blocks spans more sector than the HD really has
I use the SCSI files found on the Unofficial PowerUp support site... something is terribly wrong, right?

[djbase]

I have the default settings in the CSPPC Menu. I don't use SCSI Control.

[Framiga]

try to set the unit 1 to Synchron and Reselection (about the speed)

btw... UnitControl is showing exactly what you have set ;-)
.

[quenthal]

No need to worry about that warning message. And about the speed, just put those values in CSPPC bootmenu as Framiga suggested.

so why the freeze on syspeed???
also, it is IMPOSSIBLE to fit inside the 4000D case the 3,5" HD, do u think that a 2,5" HD converted to 3.5" will work???

ALSO, another dissapointing thing is that even though on the csppc menu I have enabled SCSI Patch, there is still a delay in boot...! I have also disabled all scsi devs except the HD and the CD , but it did not help...

No, its not, I had in my Desktop 1 HDD, 1 CDrive, CSPPC and CVPPC without problems.

I think you can fit few 3.5" HDs between PSU and your Grex PCI-board.

And for that delay in boot - what are you using with Kickflash?

[x56h34]

Grex4000D (the part of it that plugs into CVPPC connector) might be in the way if you use an 80 to 68-pin converter and an 80-pin drive. IIRC, when I installed my Grex4000D I was forced to find a standard sized (slim) 68-pin SCSI drive in order for it to fit and not hit Grex.

[keropi]

kickflash is disabled, and I use a normal 80GB ide HD + acard ... I was to furstrated with the sysinfo reboot thingie, so I did not really look if it fits in some way... it will be a tight fit though!

@keropi:

The harddrive normally fits tightly between the piece of plate going over the Zorro dauthercard and the psu, so if your psu modifications has made it wider, there will not be enough room for the harddrive.

The SCSIPatch is not loaded until the first warmboot the csppc automatically makes, so at poweron, you will still get that 30sec delay unless you build something like this.

(edit):
In the CSPPC bootmenu, for the harddrive, set to "1 LUN", "8 Transfer Offset", "20MHz Sync Period" and "Synchron".

If you have it setto "Async/Synchron", I think you need to set the sync flag in the RDB, or else it will still run it in Asynchronous mode.

The CSPPC has a 2 second delay because of the SCSI controller per default. If you in the CSPPC bootmenu, click on ID 7 - the controller, you can set the "SCSI Reset Delay" to 0 seconds. Some crappy devices might have an issue with this, but I havent come across any.

no the psu dimensions have not changed... maybe I did not look closer...

so I need an IDE-killer... I don't suppose I can buy one somewhere, right?  :lol:
thanks for the delay info, btw, I thought something was wrong. I wonder if I put the ide kill module on kickflash...

[patrik]

Atleast on the latest pictures of your psu, it looked like the uhm, side-plate (cover) closest to the harddrive was kindof bent out a bit, which would make it wider.

Exactly in which way does the harddrive not fit? Just one or two mm wider psu and you will have issues. You could try moving the psu as much to the right as possible (away from the daughtercard) and the steel plate over the daughtercard as much to the left as possible. If their screws are loosened, they can ususally be moved left<->right a few millimeters, especially the psu.

Btw, check the edit in my last post.

[keropi]

nice , gonna try all suggestions! thanx again!

I have the HD (on SCSIDE) mounted upside-down (circuit board up).  This allows the slightly larger ACARD board to fit better.  I also have a cable that includes an external wide SCSI connector so it made sense to route it that way.

I can't really help with the SCSI patch.  I ended up putting my DVD/CD-RW combo on the onboard IDE because of problems getting the SCSIDE working, cable routing issues, and reading their documentation which mentions limited support for burners.

BTW, turn off any SCSI id's that you're not using, and set all LUNs to 1 (unless you're using a CD-ROM changer you won't need it).  This will speed up the SCSI scan quite a bit.

If you want to increase the booting speed of your SCSI and have no devices attached to the IDE connector, you should disable the IDE:
 
no A4000 IDE

Annother thing:
There was something in the Cyberstorm's SCSI-settings where you could choose syncronous/asynchronous I/O mode.
I cannot remember which of the two options was the one that increased the speed of my HD oprerations dramatically - just try it out.

Either you'll notice an improvement (then your former setting was wrong - keep the new one) or an slowdown (then your former setting was correct - switch back to it).

EDIT:

I have both - my 160gB HD and my DVD-RW - attached to the UW-SCSI-Hostadaptor of my CyberstormPPC via ACARD UW->IDE adaptor and they work flawlessly *WITHOUT* any special settings in the CS's SCSI settings...
