yeah, going to send them another email today. Hopefully the should have some flash rom parts available. if so i'll buy those.

HELLO.

JUST GOT THIS THING YESTERDAY, AN E6400. FIRED UP OKDOKY IN THE STORE THEN BROUGHT IT HOME TO PUT IN A SCSI DRIVE. PULLED OUT THE RAM TO SEE HOW MUCH IT WAS, THEN PUT IT BACK IN.

LONG STORY SHORT. STARTED IT UP AND THE THING GOES BESERK!!!

IT GOES "VERIFING CHECKSUM" AND CHECKSUM ERROR AND ALTERNATES LOOKING FOR FLASH FOR FLOPPY?#$!%^WAA??

i'M GETTING THE OS HERE TODAY SO MAYBE THAT WILL FIX IT?

MAYBE i LOST THE OS BY TAKING THE RAM OUT?

THIS IS MY FIRST EMU MY AKAIS DONT DO THIS STUFF.

KC

Any chance you'd stop shouting? (writing in all caps)

You might try carefully reseating the RAM module again, but be careful and avoid static charges (hopefully you knew this already, or you wouldn't go around yanking RAM out of samplers)

And you could use this board's search function for "checksum"...

Hi,

Sorry about the caps,

Hi

so do i need the flashprep disk before the OS, maybe thats theproblem? If so, can I get a flashprep disk? how do I get one?

KC

actually i was wondering...

I dont usually get this careless but I guess I might have attached the HD without isolating it from the frame and created a ground loop possibly...

how could flash get wiped? its like a battery.

KC

Try carefully taking the ram out and reseating it and try the same with the flash. Make sure it is seated sceurely, it should not wiggle much if at all really. Make sure you didn't loosen any other connections when you were checking things out. I doubt you could have done any damage at all by removing and reinserting the ram. See if the floppy connections got loose. It won't do anything if the floppy's not plugged in. Don't go reinstalling the OS or anything, make sure there isn't a loose connection or chip anywhere inside before messing with the OS. Also try taking all the ram out and restarting it with no RAM, then 1 chip, then both. See if any of this helps 1st.

Hi

OK thats all good stuff. I think I've calmed down a bit.

yea the RAM should be seated properly. I'll check that.

I got the flashprep from the site here (duh).

you have to unzip it to install it? I"ll try that on my PC.

It was working great last time I used it, but today (hours before load in for a gig no less) when I boot it up I get the following:

- ALL LED's and the screen come full on and stay on. Screen shows nothing, just lit up.

- I can hear the HD power up and chatter a little bit like it's trying to mount, then nothing. Still spinning, but no further activity.

- Doesn't respond at all to any button presses.

I've rebooted it several times now, no change.

I'm going to pull it from the rack, crack open the case, ground myself out, and snug everything up inside (ram, proc, connectors, etc). If that doesn't work.. I dunno what to do from there.

Suggestions? Please help, I have a gig in 4 hours! =[

Same thing happened to me man. I turn it on and what you just described is happening to mine with the exception that the front led dosen't light up.





here's a pic of what i'm on about.[/img]

I have the same thing happening to me!

I just bought an E4XT Ultra with adat expansion, updated Eos to v4.7 and everything was fine.

Uninstalled the adat and internal scsi hard disk, installed my previous ide hard disk and 8 channel analog output expander from my E6400 Ultra and when I booted the E4XT the screen filled up with horizontal black lines. So I uninstalled everything (harddrive & output exp) and now when I turn it looks exactly the same as above.

I have also exchanged the power supply from my E6400 Ultra but it still does the same thing. I am not prepared to change over the cpu ram and flash though, just in case the E4XT screws that up too. It must be a problem with the cpu ram/flash or the motherboard.

Also after looking at the board in the E4XT it looks like it has been modified, there is a thin cable that has been soldered to bridge the circuit, certain connections are missing or are different to what I have seen in the adat installation manual and on my E6400.

I have found some authorised Emu service centres in London, which is handy because they are quite local to me, not sure if I can bothered to waste any more time and money on it though.

These are the UK centres.

I got the links from here, there are a few in the US too.

Anyway lets keep each other updated if anyone gets any further info on this problem.

Hi

yea I got the flashprep file thingy, but last night I just upgraded my PC RAM to 512mg and installed some softs.

I just moved into a new space and I've been setting stuff up, trying to get it into shape.

I'm in Toronto CANADA, by the way.

KC

So guess what?

I take the flashprep home and uzip it on my PC so I can put it on a floppy to put in the EMU, annnddd!!!! the soft is 1.41mg and the floppy is 1.38mg so it doesn't fit on a floppy!!!!!

whats with that?

KC

I think the floppy needs a different drive image, 1 of the posts says the floppies need to be formatted in another sampler to get the drive image. then the flashprep needs to be loaded to clean the ram then the OS needs to be loaded so thats 2 disks that need to be formatted on another machine, unless there's a formatter that can run on a PC but makes a EOS diskimage on the floppy.

Does this make any sense?

KC

Bit the bullet and swapped over my cpu flash from the E6400 Ultra with the E4XT Ultra and it booted, so looks like I'm gonna have to talk to some service centres to see what I can sort out.

you mean you took the flash right out of the other machine? I can do that with these things?

KC

Nitochrome,

It seems the only real difference in your situation is the scsi drive. By now, you tired of unscrewing those casing screws but you may want to do it one more time and take the scsi drive out, restart the machine. if all is good its a problem with the scsi drive. One thing I noticed when I installed my HD is that the 3v and 5v wires that go to the motherboard were reversed. Some tricky EMU engineering there. I'm lucky my Brother in law is a hardware/electronics freak. He picked it. See if the machine boots ok without the scsi. if it does, you have narrowed the problem down.
