The code is there to program the chip from scratch. Just select "Rage XL No-BIOS Init support" The last time I tried it it didn't work.

Their is code in xlint.c that should properly set this. Have to debug that code. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
