scsi.tex patch reduces unnecessary mismatch.
lsi.txt corrects mismatch condition.
When the mismatch happens, register ia saves the instruction address.
However, QEMU call lsi_bad_phase first, update new dsp and
then save it into register ia.
The patch correct this problem.
Another fix is in the table indirect addressing.
s->rbc is the same as s->dbc in direct, indirect, and table indirect mode.
I test 25 times debian installation automatically and there is no problem in
scsi.
The steps follow

will work well !!!
