Hello, are there known issues with some bioses not booting from Superfloppy format? All I get is the Syslinux (c) line and nothing else happens afterwords. Everything works fine if a partition is added to the device. Unfortunately however the target device can not be partitioned. Any hint?

Preferably, include the CHS geometry of the disc and its total capacity (especially if there's a trailing partial cylinder). Generally, the standard formats are the most compatible (formats listed in doc/memdisk that don't say "(extended)"). I normally stick strictly to 1440k and 2880k floppy images just to be safe and didn't start using 2880k until last year.> All I get is the Syslinux (c) line and nothing else happens afterwords.Could you provide some more details? What version are you using? What is the access method specifier code, ie, CHS in line below? "SYSLINUX 4.03 2010-10-22 CHS Copyright (C) 1994-2010 H. Peter Anvin et al" There's also EDD. Copying your entire banner line (like above) might be useful.> Everything works fine if a partition is added to the device.

It could be the BIOS, floppy controller, floppy drive or floppy disc.> Sven-- -Gene

Selon Sven Geggus <lists at fuchsschwanzdomain.de>:> Hello, > > are there known issues with some bioses not booting from Superfloppy format? >Yes there is (was?) Depend on the bios brand, sometime on the bios version. That should happen mostly for the first bioses that supported usb boot (on amd XP or Pentium IV era), not for recent motherboard. What is your motherboard/CPU, bios brand?>You usually don't need to partition the device you want to boot directly. A script has created an image that you download. You copy that image to the device with dd or more user-friendly interface. Depending how the image has been created, without partition or with one or more, the device may appear to the bios as a floppy (FDD), a hard disk (HDD), or ZIP device. It should be wise to select from bios menu the same flavor the image was created. Gilles
