Hi,
I'm confused. My Tyan s2895 has a 8Mbit LPC Flash ROM, so I thought I could not use a RD1 Bios Savior, as no 8Mbit model was available; this kept me from trying out LinuxBIOS by fear of turning my computer into an expensive paper weight. But now I see posts to this ML's archive (such as http://www.linuxbios.org/pipermail/linuxbios/2006-January/013420.html) that talk about using 4Mbit savior with the Tyan s2895.
Quid?

While the original bios needs 1MB (8MBit), LinuxBIOS requires quite less than that. So as long as you put LinuxBIOS in the bios savior chip and leave the factory bios in its original chip, everything will work fine. IOSS states that they can not be used because you can not stick another 8MBit BIOS on the savior itself.

Ah, so a smaller chip inserted in the socket will actually work, I was afraid it wouldn't. Good. Thank your for that explanation. If you will bear with me, please explain me things a bit further.
I have determined that my motherboard contains an SST 49LF080A chip for the BIOS, through the method described on the IOSS web site (run the motherboard manufacturer flash tool, it will tell you).
What if I go the other route, buy an out-of-mainboard burner/programmer and a replacement BIOS flash chip? Can I actually put a bigger one in there? Must I buy exactly the same one (from the same manufacturer) or can I buy another "compatible" chip? What must I make sure the chip I buy has/is to ensure it is compatible?
The reason I'm thinking in this direction is that http://linuxbios.org/index.php/Payloads tells me that with a 512KB chip, I'll be too tight to have Linux as a payload, but the other payloads can use only network or an IDE device; I'd like to boot from SCSI if possible.
Hmmm... I suppose I could boot from a self-burnt CD with filo instead.
