This is not mutually exclusive. My objective is bootability without reliance on specific controller. Feel free to experiment with my work.

Posted 19 January – Several functions may not work. So it’s restricted to smaller UFD sizes. See it as a case report or experiment. Each new BIOS changed the rules. dqtasheet

Stock/Availability for: CBM2096

So there was no need to ever format a ZIP diskette as “Superfloppy” see below. Partitioning is totally ignored by MBR code Bootflag doesn’t matter; any of the four primary partitions is accepted as Boot partition. You may append ” sector xx ” to the message string inside.

Does Grub4Dos really assign fd0 or fd0,0 to it??? What size USB sticks did you try. Posted 17 January – Here about ” suicide “, I mean hangupreboot or simply skip the fbinst boot record and try next boot device. Sticks contain different data darasheet their sectors. There were two drive capacities: Please find it attached.

It also works on a legacy floppy as regular PBR I created it for that purpose more than a decade ago. I believe it is the other way around, some controllers can recognise different BIOSes and behave accordingly.

To get the same drive Floppy style, MBR got hidden by just shifting each access to sectors by 32 sectors upwards. Please log in to datasehet. So it is important to test with 1GB, 2GB. You might easily ruin your harddisk’s or stick’s content, if you write to the wrong sector.

The sticks respond differently to BIOS interrogation e. Steve shows some essential aspects, how to cope with a non-booting “bootable” USB cvm2091. It’s up to the BIOS to decide, whether this disguise or camouflage was successful.

Its advantage is, that it continues booting the next boot device, when a key is pressed no infinite loop, if not removed. Posted 27 January – I’ve forgotten my password. Maybe the results of your tests reveal some important secrets of UFD booting. Mounted first partition possible as sda blocks mounting others sda1,sda If you don’t modify internal “menu. It’s output has nothing to do with the issue.

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. 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. I’m in doubt, see below. This may interest you: Sounds like you were having fun!

Posted 20 January – They took my comments and no doubt others on board. Shifting the image around is not going to reveal anything new. I need a reliable Boot process either way Do not forget the duplicated root FAT, when moving to a new location. I bet, cbm2901 did it anyway. Reliability was comparable to legacy Floppies keyword for ZIP: There is cbm201 “undo”, unless you backup best: You do it at your own risk, of course. Then try them both on all systems. IMHO the size of the whole stick not the partition plays an important role.

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. That is why I am very keen to find out what the difference is between the two hence we are left with looking at the SCSI command eatasheet that we get from the USB controllers.

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. Posted 08 September – Don’t use U3 as these are known to be non-standard. So there was no need to datwsheet format a ZIP diskette as “Superfloppy”.
