I bought a Dell DW1390 wifi card for $3 shipped on eBay, and it worked right off the bat when booted. Here is a list of things remaining to fix:
Some key mappings are incorrect (e.g. tilde key outputs an odd S-like symbol)
Battery indicator says 20:00 hours when charged, and doesn't deplete when my d-bay battery drains
Boot and shutdown is extremely slow!
If anyone has input for these, let me know.
Thanks for the help so far!
