We are getting sick and tired of paying $79-$99 for every WINDOWS XP that we install on our used computers. The Windows is worth more than the computer in some cases.
internal winmodems are hard to install on Linux systems. Since every computer that we refurbish must have a modem we have shyed away from Linux.
So you're refurbishing used notebooks, some of them really old.
As randell6564 mentioned, using modems ain't really necessary nowadays. You don't need to offer that to your clients. Just get rid of that idea.
It might be a better idea to become a reseller for a DSL company, and to offer your clients a reasonably-priced DSL connection as an advantageaous add-on.
(Just a marketing idea...
Apart from that, in the meantime, there'd be some single drivers that actually support WinModems on Linux. But I really wouldn't go for that, especially not with the broad variety of hardware you probably need to serve!
So go for DSL. - Also, none of your clients would even notice they had a WinModem on board, and even if one did, you'd never signed a contract to support it. That's not a piece of hardware being supported by that conditions.
I am currently trying to get POSTFIX to unarchive but I get error message after error message.
Ah, come on, you're mixing issues. - Post exactly what your doing, and the exact error messages, or do not post about another issue in one sentence
BTW, in order to comfort you, I'm getting "error message after error message", too - but in another computer-related field. - Someday this will stop.
- That will be the Lord's day!
Anyways, I wish you good luck, and a good rational background with any of your decisions.
As by adding-on a contract for a DSL line (earning some extra $), and sparing the costs for Windows, you could even have a much better position than before!
