I've a big problem. Of course, I made a backup of my old bios with flashrom -r oldbios.bin. Then I tried to flash my HP Compaq 615 with flashrom v0.9.1-r792 and got the following "warning":
No coreboot table found. Found chipset "AMD SB700/SB710/SB750", enabling flash write... OK. This chipset supports the following protocols: LPC,FWH,SPI. Calibrating delay loop... OK. Found chip "SST SST25VF016B" (2048 KB, SPI) at physical address 0xffe00000. Flash image seems to be a legacy BIOS. Disabling checks. Writing flash chip... Erasing flash before programming... Erasing flash chip... ERASE FAILED at 0x001c0000! Expected=0xff, Read=0xfc, failed byte count from 0x00000000-0x001fffff: 0x37386 ERASE FAILED! FAILED! ERASE FAILED! FAILED! Your flash chip is in an unknown state. Get help on IRC at irc.freenode.net (channel #flashrom) or mail flashrom@flashrom.org! ------------------------------------------------------------------------------- DO NOT REBOOT OR POWEROFF!
After reading the flash contents with flashrom -r newbios.bin I compared the old bios with the new one. They differ. What can I now do?
Best,

Don't worry, we can fix that up, I think.

[wrapping by me]
That seems to indicate a boot block lock on that chip. The last 256KB of the chip could not be erased, but the first 1.75MB are erased now.

Reflash the old BIOS after disabling the check for successful erase. Delete the "return -1" line at spi.c, line 1008.

Hi Parallix,
could you join us on IRC in #flashrom at irc.freenode.net so we can debug and fix this problem? Email is a bit slow and IRC is so much faster.

Ouch. A laptop. Laptops are unsupported because so many things can go wrong. Anyway, we're determined to fix this and we're pretty good at that.

Looks like a boot block lock. Can fix.

First of all, don't panic. There's a good chance we can recover.
First step: Copy your good backup to another external medium. Too many people destroyed their backups by accident. Second step: Run flashrom -c SST25VF016B -V superiotool -deV lspci -nnvvvxxx dmidecode (all commands as root) and mail the output to flashrom@flashrom.org (just hit reply-all in your mailer). Then join IRC and chat with us. If you don't have an IRC client, you can use the webchat: http://webchat.freenode.net/?channels=flashrom
We may need your backup BIOS image later, but please don't send it to the list for now.
Regards, Carl-Daniel
