Configuring a Sound Blaster 16 and a Gravis Ultrasound Max to happily co-exist together in Dos is how I discovered I may have a talent for IT work.

We didn't even have the term "IT" in those days.

Anybody that's never had to configure config.sys and autoexec.bat trying to find a happy combination of IO ports, DMA addresses, and IRQs for multiple devices, that all your games would recognize... man you guys *don't even know.*

Did Support for Micron PCs back in the day, and we did full system reloads over the phone, before the days of restore partitions.  So the worst reload to get on the phone was a Windows NT 4.0 reload, with an Adaptec (3940) SCSI setup and Voodoo2's in SLI with a Viper V550 AGP Card.  With the invention of HD Audio on the Seattle 2 Pentium-II Mobo, The Crystal Audio I believe took 2 IRQ's.  It was a nightmare with all of the driver CD's and you had to work a miracle to get the board to accept all of the devices as I believe it was out of IRQ's at that point with all of the extra cards..  

Kids these days will never experience the headache of DMA/IRQs/DipSwitches/Master,Slave IDE madness.   

Goodtimes tho.  Ran my Pentium II 350 @ 400Mhz from day one on a Asus 440BX P2B.  Ran a 133Mhz Bus before it was a thing.
