Is it chipset or BIOS limitation? Interesting! I cannot recall if newer BIOSes show on Processor info page, if CPU supports IVT? Do you remember what CPU you have bought it with? Does it have IVT too?
I used to work with several GX620s. I seem to remember staying on BIOS A10 (I think; It's been a long time) because A11 had a BIOS/Legacy-USB issue. But, I could be wrong. -tij-
What Legacy-USB is needed for exactly? To support old USB stuff? Do you mean, we need to mod GX620_A10 too?
Maybe; I can't remember if it was a GX280 or GX620, frankly. All I do remember is that you couldn't make selections on PXE-booted OSes until they swtiched to PM and replaced the keyboard handler. It mostly meant that if you needed to get to DOS, it was more difficult and I had to cobble together a BIOS-flashing autoexec.bat to fix the problem. I'll try and look up which PC/Axx BIOS it was. -tij-
Got PM from en4rab - he has succesfully modded GX280 - I have updated my requests post with his mod. The most important thing about it - he proves, mod can be done easily for RSDT with no free space. He moved RSDT, updated RSD PTR and fixed two places in code to point to new RSDT location. (Not mentioning common steps like SLIC injection) BIOS didn't brick without "two places" code updates letting him develop mod in two steps. en4rab, Please check, if I missed anything.
Another candidate could be GX 270 (with extra low profile AGP nVidia GF 6200) will run W7 just fine sebus
Apokrif, I think it is pointless to try to make RAID for GX620 (unless you have the tower) as desktop does NOT take 2 HDs There is a space for it (sort of, in place of floppy), but not an available caddy (as far as I could find so far) sebus
VT was added with A11 BIOS (that makes support for the whole Pentium D 9x0 range) It is separate menu under Performance, it only shows with A11 & ONLY if the CPU has VT build in sebus
Good. I can try to create mod, but it won't work, most likely. RAID mode has to be enabled somehow on ICH7R, but I have no clue who does it. Most likely BIOS does it, based on CMOS bit set, somewhere before it loads SATA ROM. Or once SATA ROM gets control, it might set ICH7R mode to RAID, but it's less likely. I hope BIOS menu is universal and disabled branches can be re-enabled (related to RAID/ASHI modes) And BIOS part loading SATA ROM, look up those CMOS bits, set ICH mode and load or not the SATA ROM. Any critics/ideas how to find it or how else it might work are welcome! I'm really a newbie in this area...
