文章详细介绍了Bochs模拟器在使用不同版本BIOS时遇到的PANIC事件问题，并提供了相应的解决方法。通过修改配置文件中的BIOS路径，解决了模拟器启动时出现的错误。

点进入系统后控制台出现下面的提示：

Please choose one: [6] 6
00000000000i[ ] installing win32 module as the Bochs GUI
00000000000i[ ] using log file bochsout.txt
========================================================================
Event type: PANIC
Device: [MEM0 ]
Message: ROM: System BIOS must end at 0xfffff

A PANIC has occurred. Do you want to:
cont - continue execution
alwayscont - continue execution, and don't ask again.
This affects only PANIC events from device [MEM0 ]
die - stop execution now
abort - dump core
Choose one of the actions above: [die]

问题原因：
在2.3.5以前的bochs使用的BIOS-bochs-latest是64k的，那个时候需要加上
romimage: file=BIOS-bochs-latest,address=0xf0000
在2.3.5中的BIOS-bochs-latest更新了，变成了128k的，这个时候配置需要改为
romimage: file=$BXSHARE/BIOS-bochs-latest

bochsrc_sample.txt说明如下：
#=======================================================================
# ROMIMAGE:
# The ROM BIOS controls what the PC does when it first powers on.
# Normally, you can use a precompiled BIOS in the source or binary
# distribution called BIOS-bochs-latest. The ROM BIOS is usually loaded
# starting at address 0xf0000, and it is exactly 64k long. Another option
# is 128k BIOS which is loaded at address 0xe0000.
# You can also use the environment variable $BXSHARE to specify the
# location of the BIOS.
# The usage of external large BIOS images (up to 512k) at memory top is
# now supported, but we still recommend to use the BIOS distributed with
# Bochs. Now the start address can be calculated from image size.

解决方法：
去掉配置文件中的address
