Wyse S10 Firmware Upgrade

Hi,

I have some Wyse s10 with firmware 6.1-6.4. I want to upgrade them to 6.5 but am having trouble.

I have the RCA_boot and RCA_WNOS for 6.5 from Wyse themselves.

I have stuck them in the ftp rootwysewnos folder. I have our wnos.ini file with autoload=2

every Wyse points to the wnos.ini via DHCP and picks up the config from there.

When i turn a Wyse on with firmware version 6.1, it picks everything up from the config but it doesnt update firmware.

when i check event viewer, the last line is checking software wnosRCA_wnos but nothing happens.

can anyone advise?

cheers
