Windows XP USB Floppy problem
One day i needed to install Windows XP on a laptop with Intel SATA AHCI enabled. I failed integrating the drivers with nLite (it’s because i used a SP3 version, instead of XP SP2 – but this is another story).
It appears that Windows XP doesn’t “support” my USB Floppy during it’s install. Yes, it sees the SATA drivers from the diskette but it fails to read them in order to transfer the file on the drive, during SETUP.
Details about my USB Floppy drive :
Freecom USB Floppy Disk
NEC Corporation
PN : 1354-508086-113-0
UF00002 rev.A
Plugging the USB floppy drive in a working system we see this in device manager :
USB\VID_0409&PID_0040\5&1ab67ec&0&1
Resolution : we need to edit a file from Windows install CD.
Edit TXTSETUP.SIF
ADD after “USB\VID_0644&PID_0000” = usbstor
this :
USB\VID_0409&PID_0040 = “usbstor”
Burn the ISO with the modified file and you’re done.

Static DHCP on CISCO IOS
After replacing a normal router with a Cisco 881K, i had to re-assign static addresses to a couple of printers (actually one – because the other has a LCD panel and i can manually enter it’s IP address).
The problem was that Cisco documentation states that after creating a dhcp pool , you just need to enter the IP address and the client identifier. Normally the identifier is the MAC address concatenated with a number representing the Ethernet media type. In my particular case, i had to use only the MAC address, in order for the printer to get the assigned IP.
"DHCP clients require client identifiers. The unique identification of the client is specified in dotted hexadecimal notation, for example, 01b7.0813.8811.66, where 01 represents the Ethernet media type, and the rest is the MAC address for the device".
