Modified: sys/pc98/i386 locore.s
Log:
Change initialize routine of Cyrix 5x86 CPU.
- Turn off BTB (Branch Target Buffer) because the BTB makes system
unstable on some machines. The BTB feature can be enabled if
"options BTB_EN" is added in kernel a configuration file.
- Change comment.
- Reorder `orb XX,%al's.
- Reset NMI F/F (mask NMI) before setting registers, and set it after
setting them. Normally, this change has no effect.
