I am experiencing a very unfortunate situation. I just upgraded the memory of my Thinkpad T450s from 4Gb to 12Gb. I actually added 8Gb to the only one available slot. 4Gb is the internal memory. This is official upgrade. The machine can reach 20Gb total memory by putting 16Gb in the external slot according to the specs.
BIOS sees the memory OK and I ran tests on it, all good.
But Haiku does not boot (no icon lit) unless I activate the 4Gib memory limit in boot manager! In that case it reports the following:
12006 Mib total, 9697 Mib inaccessible
So, it sees even less than 4Gb now.
Actually I decided to upgrade the memory because I tried to compile webkit and reached the memory limit. I was thinking of upgrading anyway but that gave the final push.
So, I feel very dissapointed right now.
I suppose this is a special situation because I know that Haiku sees much more memory normally.
Any idea or workaround?
Maybe trying EFI instead of BIOS boot (which I use now) ?
Any help will be greatly appreciated !
