Likewise, st0..st7 in the FPU could be used as a stack-like 8x64bit data storage, IIRC. I seem to remember that Pentium MMX CPUs share st* space with MMX registers however, so for those platforms one of them will have to do. //Peter _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
