So there was no need to ever format a ZIP diskette as “Superfloppy”. Posted 17 January – Posted 18 January – Then try them both on all systems.
Posted 19 January – My objective is bootability without reliance on specific controller.

See it as a case report or experiment.
Result was a true fd0 mountable floppy with Grub4dos G4Deven if there was more than one partition Linux has no problems to mount them as well, but not all at the same time. Mounted first partition possible as sda blocks mounting others sda1,sda G4D may also mount partitions as fd0,0 identical to fd0fd0,1 etc.
HDD on any of my other systems. It was recognized as HDD, but did not boot. My Way to success: There was so much space left within that single sector, that it’s possible to test datasheer code and call the display routine multiple times at appropriate datasneet.
And of course, there is space for Disk signature and complete partition table, so that you do NOT loose any other content of your USB stick’s filesystem. So I had a nearly unfiltered access to Interrupt 13h and to my stick. Steve shows some essential aspects, how to cope with a non-booting “bootable” USB stick.
You should be skilled to use a HexEditor, if you want to work in that field. I don’t like blind methods e. You might easily ruin your harddisk’s or stick’s content, if you write to the wrong sector. There is no “undo”, unless you backup best: PBR, see tools below!
Partitioning is totally ignored by MBR code Bootflag doesn’t matter; any of the four primary partitions is ccbm2091 as Boot partition. The Tool Box to share with you: You may append ” sector xx ” to the message string inside. It also works on a legacy floppy as regular PBR I created it for that purpose more than a decade ago. Its advantage is, that it continues booting the next boot device, when a key is pressed no infinite loop, if not removed.
An empty fresh formatted filesystem is easily to relocate. Do not forget the duplicated root FAT, when moving to a new location.

So if you don’t use first primary partition for booting, you might have to adapt the device name fd0,0; fd0, If you don’t modify internal “menu.
Maybe you find it useful, that no one else knows, how to proceed. There is a sample external menu. Feel free to experiment with my work. You do it at your own risk, of course. BIOS rules see Prologue. This is more or less a sophistic approach to me, not a practical. I need a reliable Boot process either way Sounds like you were having fun!
What size USB sticks did you try. This is not mutually exclusive. Iomega ZIP-Disk-Drive Iomega, the datashet of this type of removable magnetic storage medium, had in principle a good idea: The result was this layout and a hardware trick: This design corresponds to a Harddisk, concerning the Boot Records.
To get the same drive Floppy eatasheet, MBR got hidden by just shifting each access to sectors by 32 sectors upwards. So there was no need to ever format a ZIP diskette as “Superfloppy” see below.
I bet, someone did it anyway. There were two drive capacities: Reliability was comparable to legacy Floppies keyword for ZIP: Since Iomega’s ZIP drive was the de facto standard for this capacity class of storage devices as LS came up, Cbm20991 assume, that any technical difference besides increased capacity and reliability should have been avoided by the manufacturer.
There were two main drive capacities: It might be bootable.
USB(ZIP/LS)Booting with minimalist MBR code and GRLDR – Grub4dos –
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.
It’s up to the BIOS to decide, whether this disguise or camouflage was successful. Unfortunately the criteria are not foreseeable. Every BIOS manufacturer seems “to cook its own soup”, there are no mandatory specifications. IMHO the size of the whole stick not the partition plays an important role. 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. However, if you boot from them, they get logged in as drive 80h and you can use f.
FDISK to create partitions on them the latter is not recommended, though. For reference, my 3. Does someone have a Clik! This in contrast to so called “super-floppies”, which are organized like extra-large floppies, that is, they do not have a partition table in the first sector.

Some more data on them: Actually there was a third capacity: I got it from e-bay some time ago, but I have NO actual Mb media. This may interest you: Would you be able to offer an installation script or utility based on your research? You can ID chips with ChipGenius. This will prove that the contents and physical drive size are not an influence on it’s bootability.
I believe daatasheet is the other way around, some controllers can recognise different BIOSes and behave accordingly. After all they are not dumb sticks: Shifting the image around is not going to reveal anything new. What else relevant can USBDeview show?
Not only Lexar can change from removable to fixed. Run ChipGenius, then try production tools and xatasheet your booting problems may go away.
The BIOS must be interrogating these sticks and if one stick works and another does not then either:
