Hello, yes you are right, I was not using the load command before. So now I get for drive a: and b: a: 50 4f 51 45 54-33 2e 33 POQET3.3 b: 4d 53 44 4f 53-35 2e 30 MSDOS5.0 So do you think the simple solution cold be to overwrite MSDOS 5.0 with POQET3.3 and I am done? What would be the command...

How to read the same from B:? Output is: 96 04 e8 8a 60-75 03 eb

Which comands in debug would be required to read the OEM name string? Then I can compare between the 64kB card and the 2 MB card.

What don you mean? The Poquet and the 200XL do not know anything about FAT 32 (they run MS-DOS 3.30 (Poquet) and 5.0 (200LX), and my attempts to format/access the cards were just with these until now. I need to pull out one of my XP + PCMCIA notebooks and DOS/Win 9x + PCMCIA for further tests...

Next Patchday is on 14th of may.

Hello, any experts here, which know the usage of The Poquet PC? That's a MS-DOS 3.30 based palmtop, introduced in the beginning of the year 1989, so even a bit older than the well known Atari Portfolio and much older than the HP 200LX. The Poquet is quite rare, but I got a working one. Like the...

You need something to mark the bad sectors.

You should try some standard MS-DOS disks for example from Vetus. It's not necessary to use the ones from Vetus or so. Use a DOS 5 or 6.22 from there and enable EMM386.exe and smartdrv.exe from c:\dos directory. On that machine nothing special that it would need special Olivetti versions.

6.22 please...

Microsoft has released the source code of MS-DOS 4.0(1) on Github. Also older versions previously released are there. https://github.com/microsoft/MS-DOS

Smartdrv needs emm386 to be installed.

My Olivetti M380XP9 can support up to 56 MB of RAM. That is a 80486DX-33 machine. But it's not actually completely onboard... The mainboard only supports up to 8 MB, and the rest is added by up to four special 32 bit wide ISA memory cards. Unfortunatelly I don't have such cards so my machine has...

There were versions of the Olivetti M21 / M24 which came with a Toshiba 96 tpi 5.25 inch double density floppy drive, sold as 640 kB drives, but instead of 8 they also can be formated with 9 sectors reaching the 720 kb format like 3,5 inch floppies. But that is just a 8086 machine. Can you...

Yes, that is definitively a M240. Here is a picture of mine: https://forum.classic-computing.de/gallery/index.php?image/82-olivettim240/

This one might help: Maybe you can use the HOLD signal to stop the 8088. You might put a switch between the hold signal from the mainboard and the pin 31 hold of the two CPUs and a pullup to 5V. Maybe this would stop one of the CPUs. The 2nd swithch must be like above to trigger reset...
