Hi,

1/ Total newbie on QEmu-devel so please inform me if I'm doing anything 
NOT the way I should... Thx.
2/ Attached are the resyncs against 0.7.2 release for :
- the TAP device support 
(http://www.h6.dion.ne.jp/~kazuw/qemu-win/qemu-0.7.1-tap.zip)
- the PIIX4 BusMaster ATA (UltraDMA/33) support 
(http://ebisa.hp.infoseek.co.jp/qemu/arcs/qemu-piix4-udma-20050514.zip)
3/ As for the hard disk benchmark, SiSoft Sandra reports a 500% gain ! 
Althgough I'm not sure the speed increase is THAT significant, it feels 
pretty fast indeed...
4/ Greetings, bravos and thank yous  to the original authors of the patches

Feedback is welcome.

Ooopps... Little mistake here...

SiSoft Sandra reports ONLY a 400% gain.(5 times faster is indeed a 400% 
gain !)

A few details about my config :
- Host and VMs are XP SP2.
- IDE controller for the unpatched VM reports "Mode PIO"
- IDE controller for the patched VM reports "Ultra DMA Mode 2"
- Host has a RAID-0 dual ultra ata 160gb hd (nForce 4 controller)
- VMs have 4gb QCow hd file

Hope it helps...

I will update them. But the DMA patch has a problem.

For WinXP, it was the same state I have experienced when I installed WinXP
without a patch. I don't think it is related to the patch.

For Win2k, I also see the same blue screen. It says that 
INACCESSIBLE_BOOT_DEVICE. I couldn't find why.
