It died…
My graphics card has died.
Well, not entirely, but various issues with 3D rendering led me to contact both the manufacturer and the supplier. The supplier eventually got back to me with an RMA, so I posted it to them for replacement.
When I got back from the Post Office, there was an email from the manufacturer, saying could I perhaps try this BIOS upgrade for the card? Well, the answer is really no, because:
1) I’ve not got the card anymore
2) The BIOS update requires me to make a DOS boot disc. I don’t have a floppy drive, or DOS
Grrrr.
In other news, my sofa is much nicer to lounge about on now that it has a nice soft throw covering its sub-standard upholstery.
