[Coco] Using Cocodisk.exe to make bootable Nitros9 disks.

[zathrasldf]

The Sardis uses a 28 pin eprom and what's weird is that the Coco3 board I used has a 32mhz crystal and that's what caused the problems. My other coco3 board has the stock crystal and it works.  Go figure. I have used VCC as a backup of my real system, but I would love to get my hands on a CoCoSDC card but have to round up some cash first. I know of another CoCoNut that may want a CoCoSDC as well.

Hi Zathrasldf,
What type of eprom does the Sardis controller use?  I may be able to help you.  What online storage devices do you have available?  Do you have just floppy drives or do you have some other types as well like hard drives, compact flash or SD cards, adapters, etc. available for your Coco?  If you are running an all floppy system, the best way to get started is to connect the Serial I/O port on your coco (Which one?) to the serial or USB port of your laptop or desktop computer with the appropriate cable and run Drivewire 4.  I ran mine on a Windows 7 machine.  Drivewire 4 is much more reliable than the old floppy drives - even the 3.5" drives and faster too.  I was using floppy drive first as well and with I/O errors every so often I moved to Drivewire 4 for my online storage medium.  Later I expanded to Compact Flash cards on the SuperIDE Controller and on the Glenside IDE Controller with a CF Card Adapter.  Those proved to be much more reliable and even faster.  Then I added a CoCoSDC SD Card Controller with accepts SD and SDHC memory Cards which is also very reliable and faster as well.  For the real Cocos, the CoCoSDC SD Controller is the storage device I would recommend.  I don't know if any are available for purchase at the moment.  You can contact Zippster as see.    
Oops, I digressed.  I can get really wrapped up in this!  <grin>  If you have a computer with real floppy drives, you can use the Virtual Color Computer (VCC) Emulator along with a special driver on windows and make your own bootable NitrOS-9 floppies.  Make sure the floppy drive on your Windows (that's what I use) machine is the EXACT same type of drive as that on your Coco.  Incompatible floppy drives of course won't work.  Please let me know your entire situation and status of equipment and setup details so I can guide you more accurately.  I'll be looking for your email.  You might consider reading my wiki page below as I detailed how I first got started using my Cocos again.  At first, all I had to work with was floppy drives as well.  I have an ST-225 MFM hard drive from years ago I use to use with OS-9, but I could not put it back online since I have yet to locate my Burke and Burke Hard Drive Controller.  Like so many of us, it's in a box in storage somewhere.  I wish you great success getting NitrOS-9 up on your precious Coco.  Once you have NitrOS-9 on line, you will be able to adapt it in many ways.  Qaplah!  Star Fleet Out!  End Transmission!  Take care my friend.
