[sgroup] S-760 boot problem

Hi all, This is my first post to the group. I have a Roland S-760 that I've been using for a long time (since 1996). Upgraded it with 32Mbytes of RAM, 500MB SCSI hard disk and a SCSI CD-ROM drive. It worked wonderfully for many years until I had to travel to Europe in 2006. I had to live there for nearly a year. After I came back to Brazil my studio equipment have been turned off during all this time. I tried to turn on my S-760, it loaded the system from the hard disk (countdown to zero) and then it rebooted again. And the process repeated endlessly. I thought it could be a problem of the hard disk then I tried from the floppy drive. Same problem. I formatted a new floppy and wrote the system (version 2.24) and still had the same problem. I gave up and left the unit untouched. Recently I'm planning to put my hardware setup up again and I really miss the S-760 sound / programability. I tried booting it up again and had the same problem. Tried everything: removing the RAM modules, booting from floppy, hard-disk... same problem: it keeps booting up endlessly; one day I left it booting this way until it froze with the screen similar to the parameters that appears when you boot up with MODE pressed. Then I thought the problem could be of the S-760 EEPROM. Is there any way I could check this out or get a new eeprom? In Brazil the chances are really remote of finding it, I sent this unit to a technicas assistance without success. I am looking forward for any ideas and thank you all in advance for your patience and interest.
