- RAMIT Notes and Ramblings...
-
-
- This ARC represents RAMIT! Version 1.1. Please distribute it under the name
- RAMIT110.ARC. This will keep things consistent overall.
-
-
- RAMIT! is a TSR which can improve disk transfer speed on 16 bit machines
- which are forced for one reason or another to use an 8 bit disk controller
- card and use the on-card ROM BIOS.
-
-
- This ARC contains the following programs.
-
- README.RAM What you're looking at right now.
- RAMIT.EXE The RAMIT! program.
- RAMIT.DOC Detailed documentation for RAMIT!.
-
- This ARC also contains the following programs which were grabbed from
- the HDSPNTST.ARC file on my local BBS. I am including them here because
- they are so useful for installing RAMIT!
- HDSPNTST.DOC Steve Givson's SPINTEST/SPINTIME documentation.
- SPINTEST.COM A useful utility to determine interleave values.
- SPINTIME.COM Another SG utility.
-
-
-
- Other files of use for tuning a RAMIT! system available on most BBSs:
- OPTIM Program which claims to compute best interleave.
- OPTIMISE I haven't tested this one yet. It seems to use INT 13
- so if RAMIT! were installed first it would benefit from
- any such performance improvement.
-
-
- Version 1.0 of RAMIT has been tested in the following configurations
-
-
- PC Controller Old Best New Best Transfer Rate
- Interleave Interleave (KB/sec)
- --------------------------------------------------------------------------
- AT&T PC6300 WD 6 4 130

- ???? Perstor 180 PC ? ? ???
- AT&T PC6300 OMTI (BIOS-7) 4 3 189
-
-
-
- If RAMIT! cannot install your disk's ROM BIOS, use the RAMIT /W option to
- make a disk copy of the BIOS and send it to me. I can't promise I'll be able
- to do anything, but I guarantee that I'll look at it and write you back.

-
- New for RAMIT! 1.1.....
-
- The OMTI universal BIOS is supported. New options allow the knowledgable
- (dangerous) user to specify the addresses which the BIOS normally stuffs in
- vector locations 4C and 64. This makes the automatic disassembly unnecessary.
-
- In particular, the OMTI drive had too many conditional jumps to trace
- vectors 4C and 64 automatically. So I just eyeballed the code & now specify
- the addresses on the command line.
