11 * Tested on SOC sbus card bought with SS1000 in Linux running on SS5 and Ultra1.
12 * For SOC sbus cards, you have to make sure your FCode is 1.52 or later.
13 * If you have older FCode, you should try to upgrade or get SOC microcode from Sun
14 * (the microcode is present in Solaris soc driver as well). In that case you need
15 * to #define HAVE_SOC_UCODE and format the microcode into soc_asm.c. For the exact
16 * format mail me and I will tell you. I cannot offer you the actual microcode though,
17 * unless Sun confirms they don't mind.
