I just built Uwe's s1846 target and saw no output on /dev/ttyS* (serial port).
What differences should I be concerned about using the s1846 target for this motherboard 440BX based motherboard in order to get debug output? (Box acts like no bios is plugged into the motherboard.)
Which Super I/O is on the board? If it's not a PC87309 it won't work. You'll need to change the Super I/O in auto.c then...
src/superio/winbond/w83977tf/w83977tf.h appears to me it's in decimal format compared to src/superio/nsc/pc87309/pc87309.h which is in hexadecimal format. Could this be an issue?
Also, still not getting output after just editing the auto.c and replacing pc97309 with w83977tf. One thing I left out was, the ASUS P2B auto.c impliments w83977tf with the the following (0x3f0) value: #define SERIAL_DEV PNP_DEV(0x3f0, W83977TF_SP1)
Tyan S1846 uses (0x2e) /*#define SERIAL_DEV PNP_DEV(0x2e, PC87309_SP1)*/
Basically, I should be getting some linuxbios specific output on ttyS*. And filo is last with it's output right?
Btw, the w83977tf seems to have been published a year earlier then this w83977ef/ctf chip. Just scanning over the pdf files, serial pins look identical identical. -- Roger http://www.eskimo.com/~roger/index.html Key fingerprint = 8977 A252 2623 F567 70CD 1261 640F C963 1005 1D61
