And to what extent does this card have support in Linux?
Just boot up your Linux installation and take a look.
First, find the PCI vendor and device id.
- Look it up with the vendor if you can't find a box with the hardware connected,
- Or (attached to Linux) use lspci -n
- Or (attached to Windows) use regedit.exe and dig into HKLM\System\CurrentControlSet\Enum\PCI
Next, grep the driver name from /lib/modules/$(uname -r)/modules.pcimap using the PCI vendor and device identifiers.
- First column is driver name.
- Second column is PCI vendor (when grepping, prefix with 0x0000).
- Third column is PCI device (-||-).
When you've found out if there's a driver or not, you can use Google to find the documentation for said driver and take a look at whether it does whatever it is you want it to do.
