how do I verify these checksums?

how long should I wait before giving up?

10 minutes? 30 minutes? 5 hours?

with 8.10 I dont have to wait especially long.

also the fact that the gfx is trashed, suggests something is wrong,

maybe there is a bug with their gfx code, as gfx can be say 24 bit or 32 bit,

with some PCs it will be 24 bit, and with others 32 bit, if you wrongly assume
it is one or the other you will get a trashed screen.
