This design corresponds to a Harddisk, concerning the Boot Records.

Then try them both on all systems. This will prove that the contents and physical drive size are not an influence on it’s bootability. After all they are not dumb sticks: Each new BIOS changed the rules. I would like to consider those cases as an attack on some of the Open Source Softwares including fbinst. You can ID chips with ChipGenius.

G4D may also mount partitions as fd0,0 identical to fd0fd0,1 etc. Posted 07 September – HDD on any of my other systems. So if we remove the uncertainty of the USB ram size returned by the device and the data it holds in it’s flash memory, what remains must be an inconsistency between the USB devices in terms of what data they return when asked by the BIOS for Mode Sense, Read Capacity, Inquiry, etc.

Maybe you find it useful, that no one else knows, how to proceed. There was so much space left within that single sector, that it’s possible to test own code and call the display routine multiple times at appropriate breakpoints.


This may interest you: Mounted first partition possible as sda blocks mounting others sda1,sda PBR, see tools below! Is there a non-commercial utility capable of applying the same bootstrap technique? This is more or less a sophistic approach to me, not a practical. Posted 26 January – Does Grub4Dos really assign fd0 or fd0,0 to it??? Community Forum Software by IP.

There is a sample external menu. Posted 08 September – Maybe the results of your tests reveal some important secrets of UFD booting. Don’t use U3 as these are known to be non-standard.

I bet, dxtasheet did it anyway. What else relevant can USBDeview show? Iomega ZIP-Disk-Drive Iomega, the manufacturer of this type of removable magnetic storage medium, had datsheet principle a good idea: So if you don’t use first primary partition for booting, you might have to adapt the device name fd0,0; fd0, And I am not sure I am perfectly right, so do not ask me more.

Posted 09 February – If you access them through driver software, you won’t see that they are organized like harddisks, because you only see the logical drive through the driver. That is why I am very keen datasyeet find out what the difference is between the two hence we are left with looking at the SCSI command dqtasheet that we get from the USB controllers.

My Way to success: Feel free to experiment with my work.


You do it at your own risk, of course. Result was a true fd0 mountable floppy with Grub4dos G4Deven if there was more than one partition I’m cbm291 doubt, see below. BIOS rules see Prologue.


Here about ” suicide “, I mean hangupreboot or simply skip the fbinst boot record and try next boot device. They took my comments and no doubt others on board.

It’s output has nothing to do with the dataeheet. Reliability was comparable to legacy Floppies keyword for ZIP: The BIOS must be interrogating these sticks and if one stick works and another does not then either: So I had a nearly unfiltered access to Interrupt 13h and to my stick. Cbm091 re-enable javascript to access full functionality. Posted 19 January – Does someone have a Clik!

This Sandisk is prepared with fbinst and booted all other computers I have ever used.

The result was this layout and a datasneet trick: Shifting the image around is not going to reveal anything new. In a wider sense, all these mentioned legacy magnetic storage media might be called “Superfloppies”, since they had nearly or exactly the physical dimensions, look and handling of legacy Floppy diskettes.

So it’s restricted to smaller UFD sizes.
