Or if there will be one. Requires a lot of mods to a 2.2 BIOS to take advantage of some of the performance enhancments. CP/M3 is capable of doing disk I/O 10-20 times faster than optimized 2.2 systems, especially on hard disk systems. It can run with the BDOS mostly banked, and use alternate banks as L.R.U. directory caching and deblocking buffers. The deblocking is done by the BDOS, not the BIOS. There is a whole new set of utilities, it will come with RMAC, LINK, LIB, a MP/M-like SET and SHOW instead of STAT, rename with wildcards, console I/O redirection to/from disk, lots of other goodies like that. Most users should wait for their system suppliers to offer preconfigured systems, unless they have implemented their own 2.2 BIOS's. We are finding it increasingly hard to give tech-support to individuals trying to write BIOS's. I guess I could go on for a while, but I mainly know about the internals of the BDOS-BIOS interface, and not much about the enduser interface level of the system. Ask specific questions, I'll try and answer them. -jrp
