P5 optimization
BSD Process Accounting
Video mode selection
Parallel port/PC-style hardware
Plug and Play support/Auto-probe for parallel devices
...
(Character Devices)
Parallel printer support
Support IEEE 1284 status readback
I get a hang under these circumstances, but the same kernel is fine on an
AMD K6 system with a newer BIOS and a 430TX chipset. I thought I had it
narrowed down to video mode selection or BSD process accounting, but then
got a contrary result. After dozens of kernel builds, it's time to call it
a night. The results were always consistent for any given kernel on a
given box, and seem to have nothing to do with kernel size.
