3.2v4.2 System Recovery  
- Using a Linux system to recover data from a badly crashed SCO Unix 3.2v4.2 machine. As a common cause for that is simply a missing or damaged inittab, I thought we might be able to fix it by booting from floppies and doing a manual repair. Unfortunately, there were no emergency boot floppies. -

lp driver include file  
- This is the include file referenced in the sample Unix parallel port driver code. -

lp driver- debugging parallel driver  
- Includes ioctl calls to examine & set driver variables. You can speed it up, slow it down, and generally tune it to the conditions at hand. -

mount sco eafs filesystem with linux  
- Oddly enough, I was doing something very similar (extracting data from a 3.2v4.2 system using Linux) last week. It took a lot of false starts, but the eventual technique I used was: -

xenix   2012/12/16 BigDumbDinosaur
- Just to point out for those unfamiliar with Xenix, the OS itself is actually under 50, heck, under 10!. An entire Xenix filesystem can not even exceed 512M, though you can have multiple 512M fs's mounted for a total system that exceeds 512M. -

(SCO Unix)Will I have problems upgrading my hardware?  
- (SCO Unix) Upgrading memory - on the hardware side, that's easy; add the memory and run whatever your hardware uses for a setup program. One gotcha here is that many motherboards with L2 cache can only cache up to a certain amount of memory. Check with your motherboard manufacturer. In many cases, you need at least 64 kB of cache per 16 MB of system memory. From the software side, Xenix handles only 16 MB of RAM; different versions of Unix handle different amounts, so check the release notes for your version. The kernel will automatically see the additional memory, but may not put it to optimal use. There are a few kernel parameters which can auto-tune themselves within certain ranges (the best-known is NBUF), but most are fixed at link time. So the short answer is that the system will _use_ the memory, but perhaps not in the way you want it to unless you configure and link a new kernel. -

Are there any screen savers for SCO Unix?  
- (SCO Unix) Unix (and Xenix 2.3.4) have a built-in screen saver for VGA only. You have to reconfigure the kernel for this to work. It doesn't work with all hardware, but try it first. -
