Re: help writing bootable Osborne disks from stream files

Since you are new to CP/M, remember this key point. Whenever you insert a different floppy into any Floppy Drive, be sure to do a CONTROL-C to read in the new Directory structure(s) or you will clobber the floppy(s). The CP/M system has a copy of the directory in memory and if you change the floppy,...

Re: help writing bootable Osborne disks from stream files

Kenny, I'm assuming you are taking the ose-cpma_td0{00..39}.0.raw files from the .ZIP and trying to write them with the Kryoflux. When I worked with the Stream.RAW files, I would make a *.IPF file as an intermediate step. Then, I used Keir Frasier's Disk Utilities to create a Sector Dump (.RAW or .I...

Re: help writing bootable Osborne disks from stream files

David, What was the dtc command for you to write the Streaming .RAW files? Was it similar to this: dtc -r5 -i4 -fOSB001.img -i0 /fOSB001/ -w -s0 -e39 -m1 If I already have the .IMG file (Sector Dump in a .RAW type file) is it necessary to write the streamed .RAW files? What is the benefit? Thanks. L...

Re: help writing bootable Osborne disks from stream files

From what I'm reading you want the .RAW files and a .IMG file. That was what I used years ago when I used my Brother's Kryoflux. Your KryoFlux Board can read Floppy's and save the image as various formats. The INPUT File types are: Number Description Image Type --------------------------------------...

Re: Track/Side Selection when Writing?

Mark, I've seen the exact same issue with my Kryoflux. I'm using a 360K DS/DD 48TPI Mitsubishi Floppy with 40 Tracks. I get the attempt to write Tracks past 39, too! I've been using the following with my 48TPI Floppy: dtc -d0 -fMM000.ipf -w -s0 -e39 -k2 But Keir, found that I needed to remove the -k...

Dumping TRS-80 NEWDOS 80 Floppy w/KryoFlux

My Radio Shack Model 4 Computer has an Operating System named "Newdos 80". It uses PDRIVE settings to help define the Disk Layout (in Grans) and I'm wanting to create STREAM FILES (.RAW) of the Floppy. To get more information on the floppy layout, I found the the following URL: http://www....

cpmtools format of MM000.img dumped by KryoFlux

I've dumped several CP/M SS/DD 360K Floppy's as -i0 STREAM (.RAW) and -i4 MFM (.IMG) types. I am wanting to extract all the files contained in the MM000.img file and view a document. The Floppy that I created the .RAW & .IMG files from was "TRSI" SS/DD 170K Sectors (18, 256) format fro...
