Red Hat used to do so.. but it was rather costly so I think they came up with a test suite that could be sent to the vendors for a lower cost. I do not know if they still do that. The reason for a lack of a Hardware Compatibility List was that it is almost impossible to get right with modern hardware. With so many things coming with reprogrammable BIOS and FPGA's on them.. you can have 2 cards which on the outside look exactly alike and work completely differently. Having had to deal with this on video, scsi, modem, and pretty much every other card it is impossible to state what hardware really works (especially when the only way to find out that the video card has different FPGA code in it is by using an oscilloscope or something similar.) When I was getting out of the support business in 2001.. it took 2 full-time people to just certify the various systems from the main vendors because HP, Dell, Gateway might each have 20+ different combinations of the same serial-code system. And this hardware would change every 3-4 months as new boards were integrated in and others out. People I know have to do the same thing with a whitebox vendor where as far as you could tell, the motherboards and daughter boards all looked exactly the same.. however no 20 would act the same as each other until every board had been flashed with the same BIOS (and then you would find a whole set that couldn't be flashed with the rest.). > Also, when I was dealing with HP certified workstations and servers in > the past, they (HP) had to certify every part they made available for > that machine.
