Finally!!
After a couple of months of on-again, off-again trying & failing (soooo many forbidden signs and failing to find root device), I've finally got High Sierra installed on my venerable P7P55D-E-Pro with Xeon x3480 and Geforce 460. I've installed onto both a mechanical HDD (WD) and SSD (Sandisk 128GB).
It was a long and complicated road due to the ICH10 SATA controller meaning drives weren't detected or formattable by the HS installer, and when that was overcome, the new part install would fail with a forbidden sign - again, due to lack of being able to find the root device. Legacy BIOS-only makes life more complicated with HS!
I *think* what finally cracked the nut was using clover (4414) to patch the ICH file on the fly (see here for the start of the details: https://www.tonymacx86.com/threads/solved-ich10r-and-high-sierra.233435/) and very carefully making a High Sierra USB install drive *not* using the Unibeast method, but rather the insanelymac way linked to via the thread above. I've used a range of kexts (voodooPS2 et al) and a bewildering array of fixes ticked in config.plist - most of which I'm sure aren't needed. 14,2 system definition.
Once up at desktop, I installed clover 4414 on to the main hard drive as per usual, customizing the install onto the MBR and *not* the (non-existent) ESP/EFI partition. Replaced i.e. cut-and-pasted the CLOVER folder from the install USB straight over the freshly installed one.
These days I have a Focusrite 2i4 USB audio interface, which works out of the box, so there's no more hacking VoodooHDA kexts to get the VT1828S on-board sound working. Sweet.
Anyway, I'm very happy to finally have this High Sierra nut cracked on such old kit!
