Big problem after flash of SST SST25VF016B on HP Compaq 615

[Parallix]

Somewhat strage: After flashing the old bios with the suggested patch I got
the following error output:

flashrom v0.9.1-r845
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.

This flash part has status UNTESTED for operations: ERASE
Please email a report to [e-mail] if any of the above operations
work correctly for you with this flash part. Please include the flashrom
output with the additional -V option for all operations you tested (-V, -rV,
-wV, -EV), and mention which mainboard or programmer you tested. Thanks for your help!

Flash image seems to be a legacy BIOS. Disabling checks.
Writing flash chip... Erasing flash before programming... done.
COMPLETE.
Verifying flash... VERIFY FAILED at 0x00010058! Expected=0x15, Read=0x05, failed byte count from 0x00000000-0x001fffff: 0x12d075
Your flash chip is in an unknown state.
Get help on IRC at irc.freenode.net (channel #flashrom) or
mail [e-mail]!

DO NOT REBOOT OR POWEROFF!

A verification by reading the BIOS (via flashrom -r <file>) and comparing it with
the original bios (via diff) shows the same difference.

Best,

Hm. Since the erase command was disabled, this "success" is expected.

This is very odd. Can you try flashing the backup BIOS with unmodified
latest flashrom, then read back the result?

Please mail me personally at  the
following files (preferably bz2 compressed):
- original backup
- readback image after flashing with unmodified latest flashrom

I will take a look.
