Hi,

it crashes.
My bochsout after select the boot option:

When i see this error i ask in bochs mailing list and they reply me:

SeaBIOS seems to have a problem with your small image. It detects the
logical geometry 0/16/63 which is invalid, since a disk cannot have 0
cylinders.The only way to fix this is to increase the image size to minimum
1.44 MB (2880 sectors). This is a value that works here.

Is there any solution for not increase the image size of my img?
