Proteus Sound FLASH SIMM "disguised" as ROM?
Posted: Tue Nov 14, 2006 12:42 pm
Hi everyone!
I own an E5000 Ultra sampler, and an XL-1 sound module. I've been spending a bit of time looking at the sound ROM of my XL-1... physikally that is...
The printed board says: "32MB SOUND FLASH SOUND ROM"... hmmm... it seems as if the board was designed to be used with both FLASH and ROM chips....
I checked the SHARP memory chip on my XL-1 ROM... and i checked the chip number on the net... yep!... it's a 16MB FLASH chip! I guess that I've got one of the "substitute" FLASH SIMMs, disguising as a Sound ROM here... it's 16MB though, as there is space for an identical memory chip on the other side of the board... seems logical, as the ROM (read from within my E5000 ultra) loads about 15.6MB...
Surely I'd like to erase that FLASH SIMM!... and put my own samples and instruments into it! ... so I tried to auther a bank into the FLASH SIMM... E5000 says that it can find no FLASH SIMM!!?? ... what the!!....
I assume that both E5000 Ultra, and XL-1 has some sort of "ROM flag" saved on the FLASH SIMM, so that it is treated all like a real ROM... I just wonder if any of you have tried to erase such a board with success? ... I've written E-mu about this, and hope for an answer I can use... just wondering, if this "ROM checking" mechanism of E5000 Ultra is perhaps not present in earlier EOS versions, like perhaps v4.1 or something...
What a waste of rare FLASH SIMMs if this cannot be undone!
Regards, Razmo.
P.S. I'll keep you informed if I get any useful information.
