Re: CF card images
Congratulations on getting the Sol-20. Was it from EBay the other day?
I have been looking at some freeware backup programs that do sector by
backup to an image file.
Easeus Todo Free Version looked like it might do the trick. But I
tried doing a sector backup of an N8VEM-S100 compact flash and restore
from the backup file and found the CF didn't boot.
There may be a way to do this by using the linux utility "dd".
There is a windows version here:http://www.chrysocome.net/dd
you should be able to make a raw image of a CF on a USB cardreader
"dd if=\\?\Device\Harddisk1\Partition0 of=c:\temp\usb2.img bs=1M --
I have to check if this actually works. - I tried it. It seems to work
but then the imaged CF doesn't boot.
I think the problem is the usb card reader so I'll try the CF on an
IDE/CF addapter next.
I also tried with wxHexEditor but haven't got very far yet.
If I image a CF with CPM3 on it that you can restore to your CF you
sill won't have the correct CBIOS for the SOL-20.You will have to
modify John's CBIOS or, if you can get hold of a SOL-20 CBIOS source,
add in Johns IDE stuff to it.
You can do all that in the Altair Z80 simulator but you can only write
floppy disk image (.imd).
If you email me the floppy image I can load it onto a floppy with IMD,
copy it to a CF in my S-100 system, then image it up to a file (with
some program yet to be tested) and email you back the CF image file.
If anyone can think of a better way to do this please let me know.
It would be wonderfull if we had a simulated IDE drive in the Altair
simulator or were able to write directly to the compact flash from the
simulator. Maybe someone knows how to do this?
