Hallo Jim, > Still, the closer you can keep the FS to CBM specs, I think the better. Then I take this as an shameless opportunity to promote my own LBA system :) - instead of two bytes it uses four bytes to link to the next system. Four bytes minus one bit support up to one TeraByte! - it uses a BAM but without the 'free sectors/track'-byte. The BAM only keeps record of what sectors are free or not. - a directory record looks the same as the original one except four link bytes except two. - very first sector contains some system info, like the diskname, disk size, size of a sector and the start sector of the directory - the BAM starts at the second sector - the directory start after the BAM My LBA system can support 256 and 512 bytes sized sectors: if the MS bit of the 4th byte of the link is set, then this sector is the last sector of a file. The first byte, in case of a 512-bytes sized sector the second byte as well, tells the system how many bytes of this sector are used. @allemaal: Regarding X-IDE and JiffyDOS: I removed all the freed space between the original routines and none of the original routines reside on their original address anymore. Yet things work fine :) I started with removing references to the second drive. I also want to remove all references to the disk ID. As I cannot swap a disk, why would we need a disk ID? Showing the directory, the first line will display: 0 "DISKNAME " X-IDE 'DISKNAME' can be changed. Formatting of the disk can be done with and without the ID option. With ID the system only accepts the characters 'ID'. This because formatting a real disk will take quite some time. You can compare it with the quick option for DOS format. When writing this, I already removed the write protection routines. But it just occurred to me it could come in handy. Your oppinion, please! -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| http://Ruud.C64.org Message was sent through the cbm-hackers mailing list
