#67 TODO: disable beep of death at startup

on some T400 laptops, if I flash a ROM, and boot it, I hear a long beep at start up. the machine boots, but the battery light and power light keep blinking, the same like when there's a bad battery inserted.

doesn't happen on libreboot 20160907.

bisect! I have no idea what the bug is, the above is just a symptom

15:07 <swiftgeek> leah: i would enable console at spew level in coreboot, (conform it works), and then see if it happens there as well
15:07 <swiftgeek> *confirm
15:10 <swiftgeek> also linux kernel could do strange thing as well
15:11 <swiftgeek> hmm that should be easy
15:12 <swiftgeek> leah: blacklist e1000e
15:12 <swiftgeek> then load manually
15:12 <swiftgeek> if that works fine, then issue is entirely contained in this message > BAR 0: can't reserve [mem 0x000a0000-0x000bffff]
15:17 <swiftgeek> leah: google says it could be libgfxinit related, have you tried with intel vbios?

ok, according to swiftgeek this is the raminit bug in coreboot. it happened in libreboot 20160907 aswell, but we didn't set coreboot to beep/blink there.

<swiftgeek> like 90% sure

on gm45 machines (X200 T400 etc) DRAM training often silently fails then retries. Well, coreboot has a setting where when something like that happens, it will beep/blink.

I have these configs enabled:

CONFIG_H8_BEEP_ON_DEATH=y
CONFIG_H8_FLASH_LEDS_ON_DEATH=y 

I just need to set these to n. In practise, raminit usually succeeds after a few tries.
