[Qemu-devel] floppy read of incomplete sectors

[Qemu-devel] floppy read of incomplete sectors

[Jani Monoses]

[-- Attachment #1: Type: text/plain, Size: 225 bytes --]

The same issue of two weeks ago, causing some apps to fail because the last
sector is not being read if the file serving as floppy image is not a multiple
of 512 bytes.
The patch is against CVS, the new raw_block code.
