seabios 1.7.5 has about 8k free space in fseg.
|
|
|
5338af |
|
|
|
5338af |
configure 1.9.1 to keep the same amout space in fseg, so the amout of
|
|
|
5338af |
disks we are able to handle stays roughly the same. ahci + scsi are
|
|
|
5338af |
slightly below the 1.7.5 numbers but stay above the documented limits.
|
|
|
5338af |
virtio-block numbers are higher than the 1.7.5 numbers.
