Bart, Thanks. I'll create and submit a patch to mkdosfs that will warn the end user and prevent creating FAT32 partitions under 32MiB.

Good to know.

Nope, the custom boot manager is in place. SYS.COM only replaces the bootloader at the top of the volume, not the boot manager in the MBR in the first three sectors of the primary boot disk. > > At this point sys claims that it is updating the volume boot record and > > copies over kernel.sys and command.com.

Okay, will try with a bigger partition this time, formatted FAT32 via Win98 rescue floppy. Thanks Roberto! (For the kernel developers .. I'm still looking for a method to install one of those "other" bootloaders that support booting FreeDOS kernel >1024 Cyl) --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.

If mkdosfs allows you to create them then that's a bug in mkdosfs.

Hi, First, this question is better asked in the developer list (if not in the user list).
