Update: So I check some more and find this in a WYSE technical bulletin from 2005 as a step to updating firmware on the 1000 series thin clients.
3) Put the firmware upgrade files in the wnos directory created under WYSE folder
in the FTP root directory. This would be TWA_WNOS and TWA_BOOT for 1125,
STP_WNOS and STP_BOOT for 1200+, UTC_B512 for 1200.
That tells me that I do need TWA_ files yet WYSE doesnt offer them for download even though the site says: “Ver 5.2 for S10, V10L, 1200 and 1125”. Is this something I need to take to WYSE tech support or is there another answer?
