I have seen that. It figures! I do note that it still needs bits 4-6 of index 0x0a set to 010b At minimum, it will do no harm to set that on the Tyan boards.

if the init is what I think it is ( setting bit 5 in RTC index 0x0a, the divider), it should be the same for all RTC. The part that tends to differ is the PnP stuff. The index accesses from port 0x70-71 tend to stick to standards.
Detecting battery failure also tends to vary to the extent that on some tyan motherboard via chipset systems the only way I have found so far is a cmos checksum. The cmos clear jumper is actually a cmos corrupt jumper on that board. On other boards cmos clear tends to set a magic bit.
