Hi to all of you

I bought the original Emu kit 6925 CPU flash memory kit for the E4K and installed (soldered) the 2 CPU flashes according to the instructions. On startup the E4K asked for the included EOS V3.20e floppy disc to be inserted which I did. Then the E4K started to erase the flashes and hung up. I turned the power off after 5 minutes and turned the power on again. This time the display showed strange lines across which eventually faded out and left the display without any information.

I think that the program code in the flashes got erased and made the E4K unaware what to do.

I bought this kit to be able to upgrade the EOS from V3.00 to 4.10a. and to do that I had to upgrade the CPU flashes from 1 mb to 2 mb.

If anyone knows what to do here or has the program code that will enable me to reprogram the flashes, please don't hesitate to answer. I'll be very greatefull.

Best regards

hi , it seems that something went wrong with updating !!! my advice is to run the EOS 3.0 once again ( download it in the upload section ) and see what happens then >it really sounds like it's a floppy disk error , it happened to me once .so just try to turn on your sampler with the eos 3.0 on a floppy .
let me know what happens anyways
cheers

After my misfortune doing the CPU flash upgrade on my E4K I bootet her a second time and as I recall she didn't try to access the floppy drive or hd.

As far as I know the CPU flash ram tells the E4K what to do in the bootprocess but since the E4K was in the process of erasing the flash ram when it hung up I think the flash ram's are now empty leaving the machine not knowing what to do in the bootup process.

Please tell me if I'm wrong here or if you have any suggestions what to do.

Did you try with a different floppy ? i'm not sure of it but isn't it supposed to have some kind of autorun on it or something that makes the sampler read it automatically ? And what about the flashprep prog , i don't really know what it is ( cuz i run the eos 3.0 only but i know you need it with the EOS 4.0 ) but maybe that's it .ok sorry i don't know what to tell you , but try with another EOS ( even the old 2.80 ) .anyways let me know !!!

Hi again

I spoke to a technician about using the EOS software to get the flash rams loaded again and he said forget it. The flashes are empty which leaves the machine unable to do anything. That means no boot from floppy or hd.

If you ever try to update your flashes pray to god that you won't have a powerfailure or ending up with the Emu hanging up in the erasing flash process

Now I'm preparing to extract the sourcecode from an older pair of flashes to burn the sourcecode into the empty flashes. Hopefully that'll be a success. Anyway I'll let you know

I found a great offer on Ebay and I bought it.

It was the option 6855 2mb flash update kit with an option 6910 128-voice polyphony upgrade curcuit and 8 emu cd's.

Yesterday I installed the options (which by the way is not an end user upgrade) and the E4K booted up and loaded the new EOS 4.10a from floppy and recognized the 128-voice kit too.

Now I'm alive and kicking again.
