MDOS Version 7.42 Release

Have you made any changes with CYA to MDOS?

 

@InsaneMultitasker

 

I have a 1.44 MB floppy attached to the HFDC as DSK2.  It formats fine at /2 /36 /80.  It did however have a media error formatting the 1.44 MB floppy as /1 /9 /40 with a media error when it went into sector verification.  Now, when I put a 720K diskette into the drive, the floppy formatted fine with the /1 /9 /40 settings.

 

Is there any need to test commenting out those two lines of code?

Do you also have a floppy controller in the system?  The failure is only likely to occur if the HFDC is the only controller.  Sorry if that wasn't clear.   

 

Update: the CTLTYP value is used to indicate the floppy-only controller type at CRU >1100.  If there is no FDC in the system, the flag will be set to -1 and the test will branch to the error condition.  I had planned to add more types but it got way too messy. 

 

* FLOPPY CONTROLLER
*    determine controller type, drive types, and step rates
*
* CTLTYP:  0=TI, 1=Myarc, 2=CC  Default=Myarc/1
*           -1 for TIPI or NO FDC found

OK, commenting out those two lines with a single HFDC controller card in the system fixes the issue.  My HFDC is at CRU >1000.

 

Is there anything else we need to address?  If not, I can roll out a 7.43 update to fix the issue.

 

 

Nothing that comes to mind. Sounds like a plan.

Hi again,

 

Well, yes... I remapped according to what drives I have attached (one 5 1/4" and one 3.5" floppy, and two Horizon HRD's at >1400 and >1600 respectively), the path, the command prompt, and the necessary drive assigns. In any case, as a minimum, I'll have to remap the floppies to the HFDC of course, but I could try without any other changes?

I do have an original TI floppy controller available as well, if that could prove useful somehow; testing etc.

The CTLTYP will already work for two of the other DD controller possibilities, as Atronic and BwG both generally identify as CC when polled.

Now that you mention the Atronix... I just recalled I inherited one of these some years ago... perhaps I should put that to good use as well.
