USB support under DOS on intel 6-series chipstet? (Users)

posted by RayeR(R) Homepage, CZ, 23.11.2015, 18:04

Thanks for the detailed description of USB topology.
I'm also busy and have some unfinished updates to my tools waiting an years for final release :) As I use USB under DOS only for mass storage I can use BIOS service and don't see this issue as urgent problem. But for future it would be nice to make it working as there will be most of MBs with this new topology. I don't want to bother you more with it. Mayebe if Georg would like to do some testing of his DOSUSB I'm ready to assist him.

Yes, CPU doesn't matter on USB stuff, I just asked by the way. And what chipset? I have P67 and also H55 at work available for testing.

Yeah, I use SSD Samsung 840 Pro for ~3 years and it was the best upgrade experience since stepping from Celeron Tualatin to C2D and it didn't cost a lot (comparing to complete replacement of CPU+MB+RAM+VGA...). Maybe Rux. wouldn't agree and will adore latest Skylake as the only way to upgrade but from my point of view intel CPU evolution slowed down last years a lot and if your programs are not heavily optimized to use newest instruction extension you wouldn't recognize significant speed difference (just some % at same freq.) so I see far much reasonable to spend money on SSD than on latest CPU model. In my case I got my CPU for ~40% of price that similar Haswell model is selling now, so I'm happy with it. BTW can Skylake easily overclock at 4,8-5GHz? :)

DOS gives me freedom to unlimited HW access.
