[Fabrice LORRAIN]

Hello,

hdr for optiplex GX240 is not in the repo.

# getSystemId
Libsmbios:    0.12.1
System ID:    0x010E
...
Product Name: OptiPlex GX240
BIOS Version: A05
Vendor:       Dell Computer Corporation
Is Dell:      1

hdr successfuly extracted from http://ftp.us.dell.com/bios/gx240a05.exe 
to GX240A05.HDR.

updateDellBios seems to work fine (not entirely sure, because I did 
flash A05 over A05 from a remote session).
