Good news is I now have the overlay for it 'working' with the 128GB card and bootable into a single FAT32 partition with the most basic command.com and not much else.
Bad news is, this overlay means I can't directly write to the card from other machines.
Which means I can't do my usual 'copy the Windows setup folder over'.
Hence the jankery with CDs. D:
If I get this working again with the new card, though, I mean, it *does* have a 10Mbit half-duplex NE2000-clone NIC in it that I know works, for copying shit to it while running reeeally slowwwwly. But I might have to temporarily yank the sound card and shove in a PCI 100Mbit or GigE NIC if I have one in the basement.
Onboard IDE controller is so old it can't detect the DVD drive as anything, as all it knows to look for are hard drives.
Which means I'd need a controller card.
Which means I could just not use the stupid overlay to bypass the lack of int13h support.
Which means I wouldn't need the jank DVD drive setup anyway as I could pre-copy the files I need to the SD card.
Oh well, back to 'just' 8GB.
