Comment (by ttcoder):
Just booted into the r42421 a few times to test different configurations,
and indeed the situation is mostly not fixed -- but there ''is'' '''one'''
improvement. What is unchanged is this: the
home/config/settings/kernel/drivers/vesa file is still necessary to obtain
a successful bootup in VESA mode, otherwise the screen stays black (for
VESA, and nVidia). However, the '''nVidia''' accelerant is now satisfied
with having ''only'' this kernel/drivers/vesa file: once it is created, no
more need to press "Shift" at bootup to enter safemode menu and select
800x600 override.
But this does not necessarily invalidates the experimenting I had done
yesterday, with the R1A3 Haiku:
I had made some progress on the '''bootloader''' front, trying to replace
the ''haiku_loader'' file with older revisions, and indeed clobbering the
alpha3 bootloader with an older bootloader "fixes" the Haiku boot process,
allowing me to boot into nVidia accelerant without tweaking anything in
the safemode menu (aaah the joys of not having to press the Shift key at
boot :-) . The file names should tell the story:
{{{
~> ls -l /boot/system/
(..)
-rwxrwxrwx 1 user root 197424 Jul 10 20:35 haiku_loader
-rwxrwxrwx 1 user root 210928 May 16 17:48 haiku_loader.41539 (ok, like
41843 would))
-rwxr-xr-x 1 user root 210864 Jul 2 19:34 haiku_loader.42211.R1A3 (bad)
-rwxrwxrwx 1 user root 197424 Jul 10 20:35 haiku_loader.42403 (good but
with two icon rows ??)
}}}
Both experiments (new haiku build, and file-clobbering hacks) still hint
at a "side effect" of some sort IMHO... But I gotta find out for sure.
Will keep looking.
