Can you post your CF card image and your HLDRBIOS.ASM and HIDE3.ASM and I’ll take look

Hello David and Dave,

Well, here is where I am in the boot process:

assembled a new loader -> placed on sector 1
assembled new sys -> placed on 128 thru 151
used same CCP from prior DFry system -> placed on 152 thru 158
directory moved from 63 to 64

using the MasterZ80 Rom, when I boot I see everything up through the sign-on message but then no 'A>'.

looks like everything is fine up to the CCP.COM, but there is no other error reported.

Any suggestions?

Thanks,
Thomas

Hi Thomas,

you said "When you say 'move everything up by one' are you referring to loader 0 -> 1, sys 127 -> 128, directory 63 -> 64"

Yes, this is what I meant.

No, the AU entry values are the same and don't need changing because they are just a pointer to file location (in clusters of 4 sectors) referenced to the start of the Directory (sector 64)

regards

David Fry

Hello David and Dave,
This has really been a very interesting project for me and I appreciate all the help and information you two have provided.
I have looked over the attachment and it seems very straightforward to making the changes I need.
Since I obviously can't wait, I will be working on this tomorrow and have a couple questions:
When you say 'move everything up by one' are you referring to loader 0 -> 1, sys 127 -> 128, directory 63 -> 64?
What about all the AU designations in the directory? Will they all shift up by one as well?
Thanks so much,
Thomas
