Re: CMI series 3 beyond 4 gig ?

2004-11-02 by kmi9000

Hi,

The whole OS-9 filesystem (RBF) is based on 24-bit addresses for OS-9 
sectors (256 bytes). One could implement a JKERNEL SCSI-driver 
extension (for the wavesuper) in order to "fake" multiple 4GB drives 
from one large drive >>4GB, though.
As far as I know, MFX3 supported a new filesystem ("FLFS") for 
partitions with up to 200GB.

I use a SCSI DVD-ROM drive with my MFX2 system (Rev11+). A regular 
DVD-R can hold a complete 4GB OS-9 partition. Such a configuration is 
very flexible: one system drive, one 4GB work drive, and one DVD-
drive for libraries etc.
