I have 3 Dell GX520s with A11 BIOS (the BIOS upgrade labels it as a GX620 so I assume it's the same). To clarify, these GX520s are the single core 3GHz GX520s with the ICH-7 chipset.
I tried modifying the simple.map on the CD with the U2 values, but after burning the CD and booting from it, I get a pink screen of death telling me that:
Cannot set up ramdisk: Boot image is corrupted
frame=0x1402c44...
... VisorFSObj: 2165: Tar header is invalid for etc/vmware/simple.map
No place on disk to dump data...
I can include the rest of it, but that is, to my untrained eye, the pertinent parts.
At this point, I'm trying to locate a U2 install disk and will just use it to install then try the fix on the installed system.
If anyone else has been successful getting a CD with the changes to boot, please let me know how you did it and I'll try to recreate that.
