Given that ProDOS 8 only knows how to deal with 24-bit block numbers (and I'd assume that you're currently using MLI calls to read/write blocks in a partition), the limit you describe is a limit of the OS. To access larger partitions, you'll somehow need to talk to the SCSI controller directly (after identifying it first so you don't try to treat a RamFAST as an Apple DMA SCSI card) and read the appropriate block directly from the disk. I'm not sure where you'd find information on using the various Apple II SCSI cards to do direct access to the blocks on a disk...I know that the RamFAST manual, to name one example, didn't have that info in it. _/_ / v \ Scott Alfter ([EMAIL PROTECTED]) (IIGS( http://salfter.dyndns.org \_^_/ pkill -9 /bin/laden -- Apple2list is sponsored by <http://lowendmac.com/> and... / Buy books, CDs, videos, and more from Amazon.com \ / <http://www.amazon.com/exec/obidos/redirect-home/lowendmac> \ Support Low End Mac <http://lowendmac.com/lists/support.html> Apple2list info: <http://lowendmac.com/lists/apple2.html> Send list messages to: <mailto:[EMAIL PROTECTED]> To unsubscribe, email: <mailto:[EMAIL PROTECTED]> For digest mode, email: <mailto:[EMAIL PROTECTED]> Subscription questions: <mailto:[EMAIL PROTECTED]> Archive: <http://www.mail-archive.com/apple2list%40mail.maclaunch.com/> Using a Macintosh?
