Now I'll retract my *retraction*. A freshly downloaded 2.0R (1.44 Meg version) boot floppy *does* work fine). But the SNAP floppy hangs IMMEDIATELY the first time the BIOS reads it to boot (i.e., after the BIOS's seek/recalibrate sequence on each drive). At this point, it takes a hard reset or power cycle to recover. Question: I had to download a 1.44 Meg floppy version of the 2.0R boot floppy before I could get it to boot from my 1.44 Meg A: drive. But I didn't find a 1.44 Meg version of the SNAP floppy. Is there supposed to be one? Or was I correct in assuming that the same file can be installed on either kind of disk? My theory now is that BIOS (which normally detects media type from the boot sector) is being told by the boot sector that there are 15 sectors per track (like a 1.2Meg disk), instead of the 18 that are on a 1.44 Meg disk. Apparently some BIOSes don't care, but unfortunately mine seems to not like it. Anybody want to buy a slightly used BIOS? > -- > cheers, J"org private: joerg_wunsch@uriah.heep.sax.de > http://www.sax.de/~joerg/ > > Never trust an operating system you don't have sources for. ;-) Thanks, Phil P.S. - I got some mail from Dan Dartman. He suggested that I boot with the 2.0 floppy, then switch to the snapshot disk at the Boot: prompt. After a few tries I managed to do it, and the boot disk started as expected. -- ------------------------------------------------------------------------------ Phil Staub, phils@tv.tv.tek.com Tektronix Television Division (503) 627-6910
