Comment: Trying to get a flash drive up and running under DOS. When config.sys loads:
devicehigh=USBASPI.SYS /v /w
The flash drive seems to be enumerated. However, when:
devicehigh=DI1000DD.SYS
loads, I get a div by zero error message. Any suggestions? I have tried numerous switches, and also ensured that the flash drive was formatted as "FAT", not "FAT32".

Reply: (edit)Have you tried just using the DEVICE= lines as the first two entries in CONFIG.SYS ? You are using the version 2.15 Panasonic USB ASPI driver I presume ?

Reply: (edit)Hard disks have so called Master Boot Record in the first physical sector. This record contains information about partitioning of physical disk and logical disk sizes. Some USB Drives can be formatted not only as HDD, but as floppy or ZIP drive. DI1000DD.SYS presumes HDD logical structure on device, so this driver reads somewhere 0(instead of expected non-zero value) and divide by 0. You have to check format utility for your USB Drive and try to format USB Drive in HDD mode. But FORMAT command or simple format disk from Windows cannot help here, because
the trouble is in Master Boot Record (or something like this), not in Boot Sector.
