Don: thanks for offering a computer to Karen. It has an AGP slot (empty) and 3 PCI slots (empty). Not quite old enough for ISA. Someone may know how to break the WinXP password from a Linux system. If Win XP mattered, I assume that it could be re-installed. But I don't think Karen cares about Windows. If I remember correctly, Win XP doesn't have include a free-standing DOS (it is based on Windows NT). The last Microsoft OS which included DOS was probably Windows ME. I wonder if any drivers are an issue for MSDOS-7.x (what Karen seems to run). Video drivers for DOS itself are surely not needed. But for programs that try to do graphicy things, a driver might be needed. I don't know if Karen uses a program with such needs. Sound drivers are more of an issue. Karen seems to want sound. There wasn't really a standardized way of doing sound in DOS. Disk drives should just work, I think. Is the drive CD and DVD? Can it burn? The one at newegg only reads and only CDs. How much RAM? The newegg model has 512MiB -- plenty for DOS, not so much for Linux. How much HDD? The newegg model has 40GB of disk -- plenty for DOS. Karen: does this look like a computer you can use?
