Re: [Qemu-devel] Running Plan9

[Lars Munch]

Thanks Fabrice, but I still have some problems with this command.

Why is READY not set? According to the specs:

"g) Device 0 sets the DRDY bit when ready to accept any command."

aren't we ready to accept any command at this point?

Another note, should't there be a check for device 1 present?

Thanks
Lars Munch
