Hi!
If I run QEMU on Win32 with option "-fda a:", then I'm unable to access
physical floppies from guest OS. "Physical" also includes virtual drives
created by <http://chitchat.at.infoseek.co.jp/vmware/vfd.html>.
I'm also unable to boot such floppies ("-boot a"). Error message is:
"Boot failed: not a bootable floppy disk"
By doing some builds I narrowed the problem down to
<http://svn.savannah.gnu.org/viewvc?view=rev&root=qemu&revision=6677> by
Anthony Liguori.
I suspect this code:
block-raw-win32.c:raw_getlength():
case FTYPE_HARDDISK:
status = DeviceIoControl(s->hfile, IOCTL_DISK_GET_DRIVE_GEOMETRY_EX,
NULL, 0, &dg, sizeof(dg), &count, NULL);
if (status != 0) {
l = dg.DiskSize;
}
break;
Is not doing the correct thing.
Looking at the code, perhaps you should be saying -fda //./a. I don't
know a lot about windows but that sure does look weird to me.
