# Set up a prototype echo domain:
#
domain echo
program segment echo = echo
echo.dom pc = echo.pc

echo.seg add page 0x10000

echo.dom space = echo.seg

# set up a valid schedule key:
echo.dom priority = sched(8)   # normal

# set up a valid DS value:
echo.dom root slot 6 |= number(0x002b 00000000 00000000)

# set up a valid ES value:
echo.dom root slot 7 |= number(0x002b 00000000 00000000)

# set up a valid SS value:
echo.dom root slot 8 |= number(0x002b 00000000 00000000)

# set up a valid CS value:
echo.dom root slot 9 |= number(0x0023 00000000 00000000)

# set up a valid FS value:
echo.dom root slot 10 |= number(0x002b 00000000 00000000)

# set up a good GS value:
echo.dom root slot 11 |= number(0x002b 00000000 00000000)

# set up a valid EFLAGS value:
echo.dom root slot 10 |= number(0x0000 00000000 00000200)

# set up the initial entry entry block:
# echo.dom root slot 6  |= number (0x0000 0010000 1000fedc)

echo.dom accepts string at 0x10000 length 0x1000
echo.dom accepts keys 12 13 14 15
print domain echo.dom
