ROM trouble in Bochs
ROM trouble in Bochs
i keep getting a PANIC message on bochs saying: "ROM: couldn't open ROM image file '(null)/BIOS-bochs-latest' " i assume this means it cant display the BIOS? i cont it and it runs until i get a popup saying that there is a problem with device [CPU0]? how can this be corrected?
oh microsoft, microsoft, what souls you have dismayed

Find this field in the bochsrc.txt configuration file and set it up properly.
#=======================================================================
# 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.
# You can also use the environment variable $BXSHARE to specify the
# location of the BIOS.
# The usage of external large BIOS images (up to 512k) at memory top is
# now supported, but we still recommend to use the BIOS distributed with
# Bochs. Now the start address can be calculated from image size.
#=======================================================================
romimage: file=$BXSHARE/BIOS-bochs-latest, address=0xf0000
#romimage: file=mybios.bin, address=0xfff80000 # 512k at memory top
#romimage: file=mybios.bin # calculate start address from image size
The variable $BXSHARE is the environment variable... I guess thats what is not working in Bochs... So just substitute the proper path of BIOS-bochs-latest in it's place...
