Hello, I took a look at the bug 115 some times ago, you can get details on the issue with the post I sent on kernel list: http://www.mail-archive.com/freedos-kernel%40lists.sourceforge.net/msg02605.html For the bug 132, it should be different if the kernel is not a FAT32 one. But there should be some other traces than only critical error message that could help locating the problem. I would add another remark about the check for 0x0207 or 0x0408 difference, in my version of RBIL, it is set that the checks is performed only when using function for device less than 32M. But this is never the case in format code: it uses either INT 25/CX=FFFF (so > 32M call) or INT 21/AX=7305 (FAT 32) functions. So perhaps could this part of code be removed. I think it could be safer because trying to format hard-drive in case formatting floppy fails is quite dangerous...
