There are various pretty technical reasons that could cause this: BIOS and DOS disagreeing about geometry when you run SYS or FORMAT versus when you boot, use of CHS geometry versus LBA mode, use of different BIOS drive numbers when using SYS versus when booting... The latter could even go as far as 00 (A) versus 80 (C), or it can be a smaller difference such as 80 versus 81 (different "harddisk" numbers). You can use SYS with the CONFIG option to patch kernels to disable LBA or to force the use of LBA and to enable or disable whether drive assignments are shown. With my sys-freedos.pl Perl script for Linux (requires NASM to be installed, sys-freedos-linux is the name of the zip download), you can and have to manipulate the geometry, drive number and whether LBA should be used. As this is not user friendly at all, I would only recommend this if your technical curiosity motivates you sufficiently to try various of the possible settings :-) Maybe somebody could provide you with a boot sector which displays the current drives and their properties, that would be nice for diagnostic checks instead of actual booting. Likewise, maybe some tool can be recommended to display a list of drives and properties at the time when you would normally run SYS, for comparison? Note that both the partition table (of both USB sticks and normal harddisks and SSD etc.) and information in the DOS boot sector of a partition can make statements about geometry and the latter also (optionally, I believe) about the expected BIOS drive number... I hope this helps with further investigations :-) Regards, Eric ------------------------------------------------------------------------------ _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
