PC0: 720k floppy woes

[hamtronix]

Hi all -

Recently got back into the Amiga. I have a 2000 and am running WB3.1.

I recently got a CDROM to add to the system but in the proces my HD died.

I was waiting on my RAM for my accelerator and now I have it.

Here is the issue:

before my HD died I copied the PC0: over to the proper location and was able to read 720k format floppies formatted on my PC no problem. Now I copied the same PC0: over to the floppy WB 3.1 (copy) and it seems to be mounted etc. But I cant seem to read any PC floppys now. I put them in and just get DF0: ?? .

Am I missing something that may have been installed on my HD to access the floppys from PC? It seems straightforward to me. HELP

If it works you should have a PC0: Icon on the WB. Make sure you have CrossDOSfileSystem in L: and mfm.device in devs: and make sure the icon properties are correct.

You don't just need the PC0 file (or mountlist entry) in Devs/DOSDrivers (or Storage/DOSDrivers), you also need CrossDOSFileSystem (in L) and mfm.device (in Devs). There may be other bits, it's a while since I've booted my A1200, but I will do so if you don't get this sorted out.

Edit: beaten to it, see above.

I did have CD in L: but I need to check the MFM.DEVICE . I bet thats the problem. The HD came with the system so I bet those were in place before I copied the PC0: over... All the tutorials leave out everything you need to check and just say 'copy out PC0: and go to town' .. thanks guys.

What disk would i find MFM.device on?

[meega]

Workbench 3.x should have it. It might be in Storage (see my avatar).

[hamtronix]

I just checked and it is hanging in the devs directory already...

[hamtronix]

OK I have everything where it should be. At least those three files. and it still wont read the disks. I know the disks are readable because I was just using them. I do not get a PC0: I just get nothing but the DF0: ? Any other files I need to look for... man I wish my HD hadnt died. that made this stuff a real PITA.

Have you tried double-clicking on the PC0 icon?

No PC0: icon shows up with or without a disk inserted. hence the problem.

the mount file PC0: is reported as being mounted in dev/dosdrivers when I click on it.

Mount PC0: from CLI gives me an 'already mounted'

when I go into CLI and cd PC0: i get 'object not found'

also, when I put the RAD disk mount in the same directory it shows up as a drive on the WB screen. Just like PC0: ought to. Could PC0: be corrupted?

What do you mean by this? And how would I go about checking this?

Have you got CrossDOS in Tools/Commodities? (I think this is right, I haven't dragged my A1200 from the closet yet).

Does it go there or in L: ? I have it in L: . since I am booting from floppy it is a minimal 3.1. I will just make the directories and see what happens!

CrossDOSFileSystem goes in L, CrossDOS itself goes into a directory in the system's search path, and Tools/Commodities is ringing bells for me as I recall that it is controllable through Exchange...

Ah ha. I had CrossDOS the little program that will pop up with translation requestor box in L. So there is another file that has to be somewhere. I will look for i

THAT DID IT!

Thanks so much to everyone. It was the CDfilesystem not CD file that needed to be in L:

Once again you guys rock! Viva Amiga

You could also put CrossDOS into WBStartup, and then it will be run when the machine boots. The DOSDriver (PCx) which is really just a modified MountList entry, controls which device it works on, the FileSystem lives in L, and mfm.device (in DEVS:) replaces trackdisk.device (in the ROM) when it is active. It sounds complex, but isn't really. (I used to use it on my A570 CD drive with an A500+ to read PC CDROMs.)
