Details:

System: AMD Athlon 64 3000+
        motherboard ASUS A8N-*\E ACP! bios revision 1010
        display: NVIDIA GeForce 6600 (512Mb)
        memory 1Gb 400Mhz
Software:  Ubuntu (Amd_64) 5.10 Breezy
           Grub 0.95

I updated the flash bios (operating under windowsXP, using flash update
program provided by ASUS, rom file downloaded from ASUS -- see asus report
(attached) and rom file (attached).  BIOS updated to 1013. [This was done as
a suggestion from the ubuntu forums about problems in the dmesg to do with
usb support -- see dmesg attached]

Update proceeded normally.  However subsequent reboots failed with message
'no operating system'.  The partition table is OK, I can boot via any linux
CD.  The mbr shows that grub seems to have detected a disk geometry change
(I'm not sure if the bios update did in fact change the geometry).  The
problem is that the error message appears to have been written over the boot
loader portion of the mbr -- see a dd copy of the mbr attached.  This may be
either/and/or a grub problem and a problem with the asus flash update.  I
have filed a report with both sites.

Thanks
John
