3.3 The Specifics of the Host-Assisted Mode
In host-assisted boot mode the PNX17xx Series is in a configuration where an
external CPU, such as an external MIPS
In that case, the PNX17xx Series behaves as a plug-in PCI device. Most of the
responsibility of booting is taken care of by the host PCI BIOS and by the PNX17xx
Series driver. However, there is still a requirement for a boot script in order to initialize
the hardware and get it ready to act as a recognizable PCI device. In addition to the
common boot script sequence, the only extra step required is to set a:
Since these IDs are vendor specific any PCI plug-in board based on PNX17xx Series
requires an external EEPROM. This EEPROM has the responsibility to bring the
system into a good initial state (can be similar to the data presented in
and to personalize the Subsystem ID and Subsystem Vendor ID.

PCI Subsystem Vendor ID. This is a 16-bit value that identifies the board vendor.
Philips has the code 0x1131. Manufacturers of PCI plug-in cards for the open
market must obtain and use their own ID (from the PCI Special Interest
Group)[2].
Subsystem ID. This is a 16-bit value established by the board vendor to identify a
particular board. This is allocated by the vendors PCI Special Interest Group
representative. This value is used to identify a suitable driver for PC plug-and-
play.

Comments
Enables the functional mode of XIO_ACK and
XIO_D[15:8] pins instead of the GPIO mode
(default after RESET).
XIO Profile 0
Start the 8-Kilobyte data fetch from the Flash
memory device.
Waits for the completion of the 8-Kilobyte fetch.
Assumes a 32 MHz PCI clock (PCI_SYS_CLK).
TM32_DRAM_HI depends upon the state of the
BOOT_MODE[6:4] pins.
TM5250 starts executing code from
TM32_DRAM_START set to 1 Megabyte.
Start TM5250.
