As long as you don't disable device ``npx0'', the FPU will get precedence over an emulator. > Should I recompile everything for a I486? Will it make a difference? Leaving all math emulators out will make the kernel smaller, and since the kernel permanently resides in RAM, will give you more RAM. > What does this do for xwindows? > ---------------------- > device vt0 at isa? port "IO_KDB" tty irq 1 vector pcrint > option "PCVT_FREEBSD=210" > option XSERVER > ---------------------- It's an alternate console driver, you'd have to disable the `sc0' driver. Only for Xwindows, you certainly don't want to use it. It's a bit bigger than syscons, but gives you a very reasonable DEC VT220 emulation. If you seldom use text mode, this won't be an improvement for you. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
