Ok, to upgrade the EOS can be a scourge.
EOS 4.7 and flash prep that works can be found at:
http://emu4zone.basscadets.co.uk/eos1) To upgrade, you must have a FAT formatted disk.
Ideally, you should format the disk ethylene in your E-mu sampler. The next best is to format the disk in your computer.
If you format the disk in your computer, the installation often fails. Anyway it does not matter because it can be fix later, see section 5.
2) Insert dkisketten in your computer and double click on eos470.exe
When the program asks the destination, specify the target of your disk drive, generally A
EOS4.7 copied to your floppy.
3) move the diskette to your E-mu.
4) Start your E-mu sampler
Press Enter (yes) to install EOS4.7, when it asks whether to install the EOS.
5) After installation, it asks if it is to burn the EOS to FLASH. Press yes.
This applies even if the installation has failed, because you can do the complete installation in the same way and have the ability to FAT-formatted floppy disk from your E-mu.
