- I have thought about it for so long. The effort to establish a new format is

- The most important is to optimise the utilisation of the CDROM. Being a
- read only memory system, the McIntosh FS is better in being an extent based,
- but it is too far away form 386bsd.
- Maybe a slightly modified bsd FFS, can be used, with a few options:
-
- i) large block sizes, e.g. 32kbyte so that we can put 320k without any
- indirect inode pointers. Larger than this will cause too much fragmentation,
- because a fragment size of 1k will not be able to fill in the gaps.
- This method is attractive because there is no modification to 386bsd
- FFS,
-
- ii) Change it slightly to use extent based FS. I've no idea how difficult it
- will be.

- How much does it cost extra to use a new format?
- Given that a 386bsd CDROM is meant for 386bsd, there is little to be gained by
- using ISO9960(?). However the CDROM driver for 386bsd is only meant for
- Adaptec 1542 SCSI controller? I will not be able to use it!
-
- Maybe it is still safest to use ISO9960, at least I can use DOS to transfer
- files.
