Does anyone know what bugs were fixed when DRI went from 3.0 to 3.1 ? My banked cpm plus (256K RAM) works OK functionally, but, doesn't seem to provide the disk speed improvement anticipated. It seems to flush read-buffers too much, and seems to do directory checksums rather often even though the floppies are marked non-removeable. Any ideas? I use DSDD 8" (1.2MB) drives w/512 byte sectors. This is a personal project, not one of my employer. Mike Kersenbrock Aloha, Oregon

I am in the process implementing CP/M plus on a new micro
being developed. I hope someone can answer a couple of questions.
1] The system manual says that the CSV and ALV, found in the drive's
DPH can be in either bank 0 or bank 1 and yet there is no bank pointer
for these. How do they know where it is? Do they check to see if
the address is below common and assume bank 0 if it is? Could
they possibly be placed in bank 2, say?
I am disappointed that it looks like the BCBs have to be in common.
I know the hash tables can be put anywhere, but is there a way to
put the XLT, DIRBCB and DTABCB tables in another bank instead of
common?
In general, I think DR could have been a little more generous
with bank pointers in their tables. You still need too much common
if you are making a full system and have loads of tables to deal with.
2] The manual also says that a DRVTBL entry must be zero if the drive
does not exist. Could I just fill in all 16 entries with the DPH
addresses and have SELDSK return HL=0000 (as it normally would)
if the drive doesn't exist? I'd like to set up all of the fixed
tables in the BIOS ahead of time so that the system is easily
and interactively expandable. Total flexibility is our theme for this
project.

I looking for the folowing applications that run under CP/M 3.0. If any of you know where I may find these, please send me mail, or post it to the net. 1) Remote CP/M, perferably one that runs under CP/M 3.0 but CP/M 2.2 would be a good start. 2) A MAKE utility, I remember someone posting some infomation on the net about a MAKE utility that ran under CP/M 3.0. 3) A shell that may be run instead of the CCP. If you know of any public domain software that meet any of the above need, please send me mail or post it to the net. In fact even if it's not public domain, I would still like to hear about it.
