The MiST FPGA has no direct connection to the SD card, it only sees an SD emulation done by the ARM processor. Unfortunately the emulation is not very good, it doesn‘t do multi-sector transfers, for example, which my version of the driver uses. The MiST version simply has multi-sector support disabled on the DV3 level.

Was you able to test it directly with the mist ?

No, I don‘t own a MiST, but several people have tested it now.

What is for the version with the 'g' in the name ?

German.

I have interesting problem with QL-SD and Trumpcard and Gold card.
I use Minerva_1.98_io_fix_qlsd107.bin ROM.

If floppy disk present in floppy drive during the QL-SD + Trump card starting screen, I try
dir win1_ and see "not found" message. I cant see win1_ drive, only flp1_.

If floppy disk didnt present in floppy drive during the QL-SD + Trump card starting screen, I can see files on win1_. Then I insert floppy disk and see flp1_ and win1_.

This problem is same for Trump card ( TDI clone ) and Gold card ( clone ).

Can anybody check this on your system ?

Both the FLP and the new WIN driver feature auto-boot, meaning they will rename themselves to MDV if a medium is found on boot so that they are addressed when QDOS tries to load mdv1_boot. Afterwards they rename themselves back.

Now, if the FLP driver is accessed first however the WIN driver has no chance to rename itself back, you will find that it will react to MDV1 once and then is available as WIN again.

Cheers, Marcel

Hi Tetroid

I too was stumped by this behaviour a while ago, until it was explained in another thread

For this reason, I often include a WIN_USE 'win' in the BOOT file that is run from any medium other than WIN (FLP or else a virtual ROM 'BOOT' device that I use some on of my QL units.)

In fact, i believe that if you boot instead from WIN, it would be equally necessary to invoke FLP_USE 'flp' in the WIN BOOT file - to re-instate the FLP driver under its own name.

M.

Thank you very much.

Yes.

dir mdv1_
dir win1_

and win1_ works now.

I have another strange problem with Gold card, but possible problem in CPLD code incompatible with GC.
If i copy large file ( 600Kb approx ) from win1_ to flp1_ : file seems to be copyed first time.
I see this file by dir flp1_
But after reboot ( reset the QL ) I see nothing - no file on flp1_
Very strange problem.

Doesn‘t sound like a QL-SD problem to me if FLP is the device that „forgets“ the data.
It sounds like what could happen if the floppy is write protected, but then you‘d hear some yodeling from the QL speakers. Most drivers will NOT generate a visible error in this case because the write is asynchronous and the write function has already finished at this point.

Yes, I really hear some yodeling. May be floppy drive problem. I will check or change the floppy drive.

(Weird) question: would QL-SD work on an unexpanded QL with a JS rather than Minerva OS on the QL-SD EPROM?

Yes, that would work, but generally the disk size is very limited on an unexpanded QL and thus it‘s not exactly recommended.

What is the price?
