Y2K_DAYS – add N days to the system date

Because the BIOS date diﬀers from the actual one by exactly 2191 days, the setting

Y2K_DAYS='2191'

causes the ﬂi4l router to add 2191 days to the BIOS date before using it as the Linux

system date The BIOS date is left untouched because otherwise the year would be wrong

(2094 or 1994, resp.) again after the next boot.

There is an additional alternative:

Using a time server, ﬂi4l is able to fetch the current date and time from the Internet. The

package CHRONY (Page ??) is designed for this purpose. Both settings can be combined. This

is useful as it allows to correct the date via Y2K_DAYS before setting the exact time using the

information from the time server.

If you do not have any problems with Y2K, set OPT_Y2K=’no’ and forget it . . .

4.1.5. OPT_PNP – Installation of ISAPnP tools

Some ISAPnP adapters have to be conﬁgured by the “isapnp” tool. This especially aﬀects

ISDN adapters with a ISDN_TYPE of 7, 12, 19, 24, 27, 28, 30, and 106 – but only if the adapter

is really an ISAPnP adapter.

For proper conﬁguration you have to create the ﬁle “etc/isapnp.conf”.

Brief instructions to create this ﬁle follow:

• In conﬁg /base.txt, set OPT_PNP=’yes’ and MOUNT_BOOT=’rw’

• boot your ﬂi4l – the ISAPnP adapter will most likely not be detected

• Logon to the ﬂi4l’s console and type:

pnpdump -c >/boot/isapnp.conf

umount /boot

This saves the ISAPnP conﬁguration to your boot medium.

Continue on your PC (Unix/Linux/Windows):

• Copy the ﬁle isapnp.conf from your boot medium to conﬁg /etc/isapnp.conf

• Edit isapnp.conf and save your changes

The default values can be left unchanged or be replaced by the values proposed. The

relevant lines are shown in the following example:

# Start dependent functions: priority acceptable

# Logical device decodes 16 bit IO address lines

# Minimum IO base address 0x0160

# Maximum IO base address 0x0360

# IO base alignment 8 bytes

# Number of IO addresses required: 8

1) (IO 0 (SIZE 8) (BASE 0x0160))

# IRQ 3, 4, 5, 7, 10, 11, 12 or 15.

# High true, edge sensitive interrupt (by default)

2) (INT 0 (IRQ 10 (MODE +E
