Amiga 4000 no boot 8Gb CF

[arttu80]

Hi all!

My problem is with 8Gb CF-card. Booting fine on my A1200/030, but when I connect it to A4000/040 via standard IDE cable and el cheapo IDE-CF adapter it will recognise card when I cold start it, but after reboot it disappears.  Since it's supposed to reboot once, before WB loads, I can't get in WB on my A4000. So I suspect too long a cable or should I try tweaking CF card?

On a side note, standard FFS 4gb CF's working fine..

[arttu80]

Before the reboot you probably load an A1200 scsi.device. This does not work on an A4000, you have to replace it by an A4000 scsi.device.

Thanks, but pardon my software weakness, how'd I do that? I should tweak it in HDToolBox?

Anyway, for now I'm out of this game since I managed to fry my 8Gb CF while trying other CF-IDE adapter (while in serious influence of holy beer)... I plugged 4-pin power connector backwards. Luckily my 4000 endured this ordeal!

P.S. And yes, there was real smoke from CF card! Well, some excitement and fireworks with my beloved computer.

Here I'm at it, again.

Received 16Gb CF card. Same thing while booting in A4000. Working fine on A1200.

Soo, I can see there is a line in startup-sequence file "c:LoadModule devs:scsi.device"

I checked scsi.device version, which is 43.47. Is it correct while using on A4000D with 3.1 ROMs?

[arttu80]

Hmm, still I'm looking for someone who actually have some advice about what scsi.device file I should use on A4000D with that CF card and where I can get it?

Actually I'm little surprised at how difficult this simple issue is to solve. I googled hi and lo, but no firm answer on this...

[arttu80]

Well, where did you get this one from?



The same source should have the one for A4000.

Well, just one guy selling these here locally, but I'm sure he's not up to it so that's why all the hassle... And I'm confident he wouldn't have written these .device files himself so they must be available, right?

scsi.device A4000 anyone?

[arttu80]

Hi there, again.

I tinkered some more with my 4000. Even tried to replace scsi.device (43.47) with 43.45 and lesser versions, but no luck. It seems, after LoadModule command machine reboots and loses scsi.device completely as witnessed by loading SysInfo4.0 from floppy disk and checked loaded devices, it didn't show scsi.device at all.
When I bypass LoadModule command, machine will boot but show dh1 as NDOS disk, since it's out of 4gb range. Filesystem is PFS3.

Is there different version of LoadModule command or substitute to it I can try?

[arttu80]

Whew, I think I'll be stuck with this, because I don't see any scsi.device files available separately for A4k, so I'm reeeally starting to think it's hardware related problem I have with bigbox...

Maybe something to do with memory allocating while using LoadModule command? Have tried REVERSE and HEADERFORWARDS options with it, no luck.

This sucks, because really looking forward to expand this baby with some new HW, but 4Gb won't cut it.

As for swapping CFs between two machines, wasn't my objective. Just keeps me wondering why not working with 4000.

[arttu80]

It's Workbench 3.1 and SCALOS setup on top of it. Not OS3.9 I'm using. Therefore no such thing as "Amiga OS ROM Update" in Devs.

Maybe I should go to the length of trouble and install that darn 3.9 to get rid of this miserability.

[arttu80]

I'm not familiar with what SCALOS does or does not do, but 3.1 natively does not include support for hard drives greater than 4GB.  You'll have to install one of the various patches / patch methods to support hd's greater than 4GB if you intend to stick with 3.1.

But this very same card working flawlessly on my 030/KS3.1 A1200. So I don't think it's missing any patches. Only difference I see, is IDE-CF adapter, which ofcourse is different in 1200 (using smaller 2.5" IDE standard).

If this problem is really in scsi.device file, so why don't I see separate files for 4000 available anywhere?

Actually it's beyound me, why nobody with 4000 ever encoutered this same problem and had it solved...

Lots of info out here, but here's a good thread that might help you:  http://eab.abime.net/showthread.php?t=32256

This line revealed where I could get darn scsi.device file for A4000!!! ;

"Open up Dopus and in the left window go to the “MyFiles/LargeHD/128GB Support/SCSI_IDE_43_24/Patched” drawer and in the right window go to the “Devs” drawer."

So thank you thank you so much for helping me out in right direction, now she boots fine with this 16Gb card!

Unbelievable, this file was here on this card all the time, but I couldn't find it before. So indeed it was just what I really needed.

Now got that extra motivation to tune her up. Finally will tinker with my newly bought Indivision card to get some hi-res Worbench pleasure!
