Hello I recently tried haiku OS on my old laptop the Dell Latitude D500. PDF by Dell with the machine Specs.
The laptop’s internal wifi card works. It uses a intel Pro/wifi 2100. It will work using the closed source driver. See install-wifi-firmwares.sh here.. However wifi card is failing due to age all the time and thus i do not use it.
I have not gotten my TP-Link TL-WN722N wifi adapter(using the atheros AR9271 chipset) to work. (Do wifi adapters even work?)
For graphics it uses the 855gm graphics chipset and that requires i start the computer using failsafe graphics. Restricting me to a bad refresh rate , 640x480x16,800x600x8,1024x748x8).
Ethernet using intel Pro 10/100 works perfectly.
For sound it uses the Intel AC97. Have not tested it.
