Already have that one, just the FX data sheet wasn't linked anymore, though you find it if you use the search facility as others have pointed out. /Daniel --

Logo contest started.

Dear OpenBIOS readers, as you might have read already, we don't have a logo for our project yet. If you feel that you have an idea how to design a nice logo, go and check out http://www.freiburg.linux.de/OpenBIOS/logo/ As soon as we have some logos, you will be able to check them out and vote for them on the same site. Daniele, could you please announce this on freshmeat and slashdot? :-) Happy phacking.. Stefan. -- "Under capitalism, man exploits man.

Hi I run a small IRC network, called CMDnet, we have services, and have quiet channels, you are welcome here if you want. Full server list can be found at www.cmdnet.net, or connect to irc.cmdnet.net. Yours Matthew Stefan Reinauer wrote: > Hi guys,.. > > you might be interested in this.

OpenBIOS on IRC

Hi guys,.. you might be interested in this. I just "founded" an IRC channel #OpenBIOS on IRCNet. Would be nice to meet you there.. Maybe it could be useful to discuss some things online... I have a screen session running, which is detached almost all time, so don't think I ignore you if I don't answer immediately. Stefan.. -- "Under capitalism, man exploits man.

Parallel Port EPROM simulator
by Qiwei Xiao 23 Nov '98

Parallel Port EPROM Simulator Copyright 1998, Qiwei Xiao (qiwei(a)qiwei.net), All Right Reserved Free for noncommercial use. Absolutely no warranty of any kind. Note: IC1, IC2 and IC3 (74ACT541) can be replaced by two 74ACT841 to save one IC. For a PC parallel port, the control output (base+2) has 4 lines: C0-C3. They are open collector so you might need a pull-up resistor for each of them. C5 controls the state of bi-directional data port: if C5=0, the port acts as an ordinary output port; if C5=1, the output port is in high impedance state (and effectively becomes an input port) so any outside source can drive the bus and can be read in. A good PC parallel port tutorial is in http://www.rmii.com/~hisys/parport.html. How it works: C5=1, C1,C2,C3 = 000: Normal Mode The simulator acts like an ordinary ROM. The extra ICs on the bus add about 5ns delay which shouldn't be a problem for FLASH chips whose delay is typical in the 70-100ns range. C1,C2,C3 != 000: Programming Mode (C1,C2,C3 "park" on 111) Read operation: (1) Set C0=1, then C5=0. Order is important. (2) Place address byte 1 on the data port, send a pulse to IC7 to latch it. (i.e., C1,C2,C3 = 111 -> 011 -> 111) (3) Place address byte 2 on the data port, send a pulse to IC6 to latch it. (4) Place address byte 3 on the data port, send a pulse to IC5 to latch it. (5) Set C5=1, then C0=0. Order is important. (6) Read in data. Repeat the steps so all the data are read in. High address byte needs to be changed once for every 256 low address byte changes. Write operation: Same as read operation, the only difference is in step (5): (5) set C5=0, send out the byte to be written on the data port, and send a pulse to the "Write Enable (WE)" line of IC9.

M, Let me know when you have an IP number for this machine, and we can check resetting our DNS pointers to access it and get things going. BTW, Happy Thanksgiving - even it if is not a national holiday for all of us, it is a nice idea to take some time in appreciation of how this planet is so supportive and convenient of our life-forms - almost like it was planned, eh!

> Thanks to M. Carling for his work. You're welcome. My thanks to Todd Whitesel for bringing to my attention a nasty typo. An update version is available at ftp://209.157.87.155/pub/openbios/FAQ I just built this machine yesterday, so it's not in DNS yet. I bought a 4GB drive for it, it gets backed up regularly, and is sitting on an underutilized T1. As soon as I finish getting it configured, it can serve ftp, http, and cvs for OpenBIOS. The machine won't be used for anything else, so it would be suitable for it to be ftp.openbios.org and www.openbios.org. I'd be happy to work with John Foster to make this happen, and to make sure that any concerns he may have are met.

> For the EPROM simulator: It will cost about 450,- DEM (~ $290) to build, That seems optimistic. Anyway, I know someone who owns a ten-person company that manufactures such things, primarily for the embedded market. He's getting excited about OpenBIOS, and I think he's just about talked into donating a few. M
