Re: [coreboot] x201t + windows7

[Zaolin]

Hi,

have seen the same problem on all thinkpad product types supported by
coreboot.
Maybe someone should get a Windows Developer Edition
and solve this bug ;) .

Those are called "checked builds" and are freely available to students 
through Microsoft's DreamSpark program.
In addition to that you'll need another system running WinDbg (on 
Windows), and an EHCI USB debug or serial connection (no pci* serial 
card with mmio, it needs to use io ports).

Most of the issues I've seen so far were somewhat ACPI related (except 
for one due to a messed up Int10 handler, ie VGABIOS), and I collected 
some bits and pieces on http://coreboot.org/ACPI.
ACPI debugging is _much_ more powerful with checked builds than without, 
but for other issues the additional asserts, symbols and lower 
optimization level are useful, too.

However they're of limited use when trying to find issues in the 
installer, since that (at least up to Win8) is non-"checked" even on 
checked build media.

x201t + windows7

[Alexander Couzens]

Hi,

I got a checked build as well as a working `original` usbdebug device (thanks to peter and cristi).
My windows got nice after I disabled lowmem with `/lowmem`.
What does this means? I thought this might be a problem with the memory map? Or pci management?
Missing out a memory block to mark forbidden? VideoRAM? VBIOS? [...]

I've disabled a workaround for grub to free SeaBIOS from marking 0x0 - 0xfff as RAM.
But doesn't help.
I still get a bluescreen '... stop 0x7e'. The internet suggest a look on (video) drivers.

Ok, I forgotten this.  I'll take another try with my hdd win 7, maybe it gives me more information
with usb debug than the installer does.
Another thing on my list is disabling and hide useless pci device.  Starting with ethernet ;).

@Patrick: any further suggestions?

Thanks,
lynxis
