With the SUP720 I have not had any issues with compact flash cards formatted in windows. The supervisor supports FAT 12 and 16.
I just tried to format both Compact Flash cards and here is what I get when I try and boot from rommon.
rommon 1 > boot
boot: cannot determine first file name on device "bootflash:"
rommon 2 > boot disk0:
device does not contain a valid magic number
boot: cannot open "disk0:"
boot: cannot determine first file name on device "disk0:"
rommon 3 > boot disk1:
PCMCIA disk1: device is not initialized
open: read error...requested 0x4 bytes, got 0x0
trouble reading device magic number
boot: cannot open "disk1:"
boot: cannot determine first file name on device "disk1:"
rommon 4 >
The only supported compact flash cards are the ones from cisco. There are some third party ones that do work. It is not recommended to use them. Did either of the CF cards work when the switch was booted?
San Disk are the Cisco ones....peal the label off and they are SanDisk. These were working and the switch was booted and now they are not...they have been working for years.
Is there another 6500 that you can use to format the cards? I'm fairly certain the cards I use were formated and files copied by my laptop.
