Here is what I did to integrate this into linuxbios. I created the following file src/mainboard/via/epia-m/smbusenable.inc /* Useful macros PCIBUS, and SMBUS functions for getting DRAM going. */ /* courtesy Eric Biederman of linuxnetworx.com */ #define CS_WRITE_BYTE(addr, byte) \ movl $add

Hi Dave, Have you checked out the clock connected to LPC? On W311, FS2 can be set to 24 or 48 MHz. It could be the problem, since I have similar problem with USB on a custom cle266 board. FYI, it can be programmed thru smb. Here is from we have done to program the USB clock. #define SMB_BAS

I don't know what the problem is, I don't have an EPIA-M yet. One thing you could do with a PCI analyzer is watch the ins and outs and look for a magic setting. Are your sure the clock source for the superio or uart is the same for linuxbios and award? disassembly is a bad idea. The "emula

2003-12-17 Thread Dave Ashley
I am at my wits end regarding how to get the serial ports on the epia-m to run at full 115,200 baud rate. Here is a summary of what is known: 1) The serial ports are driven by the VT1211 superio chip. 2) Under AWARD bios the serial ports are capable of 115,200 operation. 3) Under linuxbios they ca
