This happens only on IBM/Lenovo laptops (tried a few models), while it works just fine on any other desktop or laptop I can get my hands on. Probably has something to do with bios...

If there are no other suggestions, do you think it would be possible to use IBM bios with qemu ? BTW, I did not manage to find this error message ("A disk read error occurred" in the sources - neither qemu, nor bochs bios. > > Samuel > > > ^ permalink raw reply [flat|nested] 8+ messages in thread

What's an LBA28 issue ? 2^28 sectors = 128GB, beyond that bochs bioses before around beginning of 2008 can't access data. Samuel ^ permalink raw reply [flat|nested] 8+ messages in thread

The Host Protected Area makes an IDE disk look smaller than it is to the system, maybe that can cause such errors? Andreas ^ permalink raw reply [flat|nested] 8+ messages in thread
