If you can imagine doing a system call for every line that you want to draw and also a great opportunity to lose your scheduling;then, yes moving the device specific ddx layer to the kernel is feasible 8) To Josef: XFree86 has specific "drivers" for vga cards which know the vga card at the register level and at that level rarely do two vga chipsets have the same low register level interface;additionally, the vga "driver" has to know about : ramdac, max clock setting, and monitor specifications. It can be done however I don't think is worth it. Just Run X. The system fails while on X attach the console to a serial port or better yet write a gdb interface to ethercards . I used to work at HP and they had a cool networked kernel debugger so in principle and by example it can be done. -- Amancio Hasty hasty@rah.star-gate.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
