Hi all, My project has 2 unsolved problems: Com ports and PC speaker. I run it on a Kontron MopsLCD7 board (PC104) + a ComputerBoards 2 x RS232, 1 x LPT add-on board (also PC104). Target XPe has PC definition from Kontron (formely Jumptec), and have added Plug and Play device enumerator. Serial ports are configured like: 1. Com4/Irq3 (Add-on board) 2. Com3/Irq4 (Add-on board) 3+4. Auto (PC board) Bios reports 4 Com ports after boot-up, 4 are also in Device manager, but Com1 and Com2 (they are reported as "working properly") have banned the Irq (Irq used by Com3 respectively Com4). I have tried different configurations for both boards, with and without Plug and play OS in Bios, with and without Secured Setup Configuration (Bios), nothig help to put all 4 Com ports at work. Second problem is with the PC speaker. There is listed in Device manager a "System speaker", it is also in the Target designer project, but the speaker output does not work. I have tried the same device with Win NT4.0 (our previous SO) and all work just fine, so no hardware error can be considered. Thanks in advance for any idea. Florin Petrov Osypka Medical GmbH
