wimboot not showing windows 8 logo

[cckp]

when booting windows 8 PE with latest wimboot 2.2.4, I found that wimboot does not show windows 8 logo.
it shoes something like booting windows 7 instead.

then I tried many versions from git.ipxe.org/releases/wimboot
just found that some verion wimboot won't show windows 8 booting logo, the blue big window,
but some version does.

1.0.0 cpio error
1.0.1 cpio error
1.0.2 cpio error
1.0.3 ok
1.0.4 ok
1.0.5 error
1.0.6 error
2.1.0 error
2.2.0 error
2.2.1 error
2.2.2 error
2.2.3 error
2.2.4 error

with same 4 files : bootmgr bcd boot.sdi boot.wim

kernel wimboot
initrd /boot/bootmgr bootmgr
initrd /boot/bcd bcd
initrd /boot/boot.sdi boot.sdi
initrd /sources/boot.wim boot.wim

wimboot of version after 1.0.3 all can boot windows 8 PE.
but only version 1.0.3 and 1.0.4 can show windows 8 LOGO.
but latest wimboot support UEFI. and it shows windows 8 LOGO under UEFI.



so to boot windows 8 PE with win8 LOGO, must use wimboot 1.0.4/3 with normal BIOS,
and use wimboot latest 2.2.4 for UEFI

interesting. don't know why.

That's not an error. It's a side effect of the workaround that wimboot applies for the bug in Windows 8 (and Windows Server 2012) to ensure that error messages can be displayed without having to guess the correct set of font files.

You can disable this workaround (which will result in your seeing the normal Windows 8 logo) by adding the "gui" parameter to the wimboot command line; see http://ipxe.org/wimboot#displaying_graph...t_messages.

oh I remember I have seen this parameter and used it for some times. then I found "pause" parameter more useful and forgot the "gui" parameter. and I don't know exactly the real behavior of the "gui" parameter. now I see. thank you.
