From the web I found that HCL says that Realtek 8139 NIC is now built in the Solaris 10 kernel and doesn't need any external driver. However, my D-Link 530TX NIC doesn't seem to give me any "rtls" in "dmesg". From solaris-x86.org I found a tutorial that says download external rtls driver from Realtek and I did that. After running "sh Install", it says installation successful but devfsadm failed. After reboot still no luck, I don't see any rtls in ifconfig or dmesg. Furthermore, I'm worried that since the driver only claims to support Solaris 9, would it corrupt my system, if so how do I re-overwrite it with the correct driver, if any? All I need is to bring up the NIC so that I can talk to a ADSL modem, thank you.

First try,
You also need to disable PnP OS or ACPI in BIOS setting otherwise it will not work same applies to some old bios on FreeBSD for rtl chipset so please disabled it

If that not works then
For DLINK NIC built in driver as well as one from realtek failes it is true that it works with other NICs the soulution is to get driver from following url
http://homepage2.nifty.com/mrym3/tai...-1.0.5a.tar.gz. This driver works with Solaris10 build 72 or higher. Read the READEM.TXT in the tar.gz file. You may also need to install gcc or sun c compiler.

Hope this helps
