I've pretty successfully ran FreeBSD and booted from a floppy with minimal participation in windows, enough to write a *FreeBSD* boot floppy (rawrite.exe, fdimage.exe) who cares what MS is doing as long as one of those two programs still works (seriously though, I think we'd all be better off without windows 98) =) -Pat ___________________________________________________________________________ Pat Lynch lynch@rush.net Systems Administrator Rush Networking ___________________________________________________________________________ On Sat, 27 Jun 1998, Matthew Thyer wrote: > This situation has just become more urgent with the release > of Windows 98 which I have just installed over the last several > hours. > > Now a command line only boot of Windows 98 (i.e. hitting F8 before > Windows boots and choosing command line only from the menu) cannot > run fbsdboot.exe without the crash just as I feared. > > Now the only way to use fbsdboot.exe is to boot off a floppy disk > that has been created with Windows 95 or earlier. > > I suspect that a Windows 98 startup disk wont help but I haven't > tried that yet. > > So there is no way of booting cleanly using a version of DOS from > Windows 98 (and beyond probably).
