You forgot a pointer to new disk image ... I don't know anything about problems with FXSAVE/FXRESTOR instructions even in Bochs 2.1.1. There were bugs in FNSAVE/FNRESTOR FPU instructions but they already fixed in Bochs 2.2. I don't know why you added nofxsr option (which is related to FXSAVE/FXRESTOR P6 new instructions) but you could already drop it, it will work only better ;) Stanislav -----Original Message----- From: Ken Barr [mailto:kb...@mi...] Sent: Friday, April 01, 2005 11:04 PM To: Stanislav Shwartsman Cc: boc...@li...

I replaced the image with one that has a better grub menu and a fix to /etc/mtab. It doesn't feel like it's reliably getting me to a prompt or login, I don't know how to tell if it's deadlocked or just slow. The kernel options are: nofxsr (don't know if new Bochs has fixed its floating point save/restore instructions) noapic For compiling, configure bochs with --enable-cpu-level=6 --enable-num-processors=4 The .bochsrc that I use is below: ------------ romimage: file=BIOS-bochs-4-processors, address=0xf0000 vgaromimage: file=VGABIOS-lgpl-latest megs: 32 floppya: 1_44=/dev/fd0, status=inserted floppyb: 1_44=b.img, status=inserted ata0: enabled=1, ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14 ata1: enabled=1, ioaddr1=0x170, ioaddr2=0x370, irq=15 ata0-master: type=disk, path=c.img, mode=flat, cylinders=1117, heads=16,spt=63 ata1-master: type=disk, path=swap.img, mode=flat, cylinders=520, heads=16,spt=63 boot: disk ips: 10000000 floppy_bootsig_check: disabled=0 log: out.bochs panic: action=ask error: action=report info: action=report debug: action=ignore debugger_log: - parport1: enabled=1, file="parport.out" vga_update_interval: 300000 keyboard_serial_delay: 250 keyboard_paste_delay: 100000 floppy_command_delay: 500 mouse: enabled=0 private_colormap: enabled=0 keyboard_mapping: enabled=0, map= ------------- > P.S> Text problems already fixed in CVS, you could get latest CVS snapshot > from Bochs website and it will work correctly.
