"the original dots are set to accept only the original linux OS. if you change the partition sizes or any other thing the system will not work. if you have a modified one,no problem.just install the OS and done.

I donīt know if you can run any other OS in an original dot station,Iīve posted a question in our forum,so the people that had one of the original dots will tell me if they succeed in that (theyīve trying to f*ck up the bios for 5 months).

I'll write you again with more info when i get it."

So, if anyone hasn't bought one, you might want want to till we figure this out.

Can those who have bought units sound off?

My AOL (Spanish name for the Dot.Station) is in transit, should get it in a couple of days. If the BIOS is going to be the problem, and can't reflashed it ourselves, we may be able to have it reprogrammed like the iOpener.

Ok after talking to the gentalman from Spain he told me that all the people on that spanish board are purchasing thier units from this site.

Maybe someone who knows spanish can talk to the seller and see if we can score some suggestions. Maybe the seller would sell bios ships even. dunno but worth a shot.

If the problem lies in the bios., then we might be ok. I recieved two different bios at home last night that I haven't had a chance to post.

Opening it now.

- The keyboard has a few spanish words on it.

- The power plug in the box looks like a washer machine cord. Just use a regular old cord. Power is 100 - 240V CA; 3,4 - 1,8A; 50 / 60 Hz)

- As for the security hex, forget about it. I broke all four center posts off accidently trying to use a flat head in the head.

- The OS is Spanish.

mines apart.

MB looks pretty standard.

Both primary and secondary ide connecters are connected.

Found it intresting that unlike the vegazone disassembly pics, this unit has a removable plate in the front that looks to be where the cd-rom drive would go in future versions.

Verified unit comes with 64mb pc100 ram not 128.

Bios soldered on-board.

MHeadroom, so it *is* a separate EPROM for the bios? What's the chip? I was getting bummed out by reading the D810EMO board spec, since it talks about the BIOS being a 512kB area in the "82802B firmware hub". SMT rework I can deal with...

Kludgemeister,

Sorry, I should have been more clear. I had not read the intel specs on the board. What I ment to state is that it is not a socketed chip, but if I had don't my homework I would have known that already :) My bad. Board specs look to be correct.

That's OK, MHeadroom. You're about 5 days ahead of me already. My Dot isn't arriving until Monday.

Is the 82802 chip a 32-pin PLCC? If so, is there enough clear space around it for a socket? (I fixed a motherboard with misflashed BIOS (my own bad) last week by unsoldering the chip from the m/b, adding a socket, and flashing the chip in the EPROM programmer at work.)

I've done some more reading, and found that a compatible BIOS chip is the Atmel AT49LW040. Unfortunately, the EPROM programmer at work does not handle this chip. On the other hand, a flashing utility that handles the Atmel might also handle the 82802.

On the Linux side, there is a project called flash_rom that will flash 82802ab chips. I don't know if that would be applicable, since it appears to be aimed at doing embedded Linux.

BTW the datasheet for the 82802 chip is at http://www.intel.com/design/chipsets/datashts/29065804.pdf

Kludgemeister,

excuse my ingorance. 82802 is 32 pin but I don't know what PLCC stands for. As far as the ability to ad a socket. I don't think that should be much of a problem. there is about 1/4 inch clearance in all directions. hope this helps a bit

PLCC is like a surface-mount chip, except the pins are bent under instead of flaring out. It has pins on all 4 edges. PLCC stands for "Plastic Leaded Chip Carrier". I had to look that up!

That's good news that there is space for a socket. Good news! The BP Microsystems programmer at work handles the 82802AB chip (it calls it an "E82802AB" which is why I overlooked it at first.) When my Dot arrives the first thing I'll do is pop the chip off and back it up to a disk file.

Things are starting to look up after all!

hello, im the spanish guy, have more info. our friends here that have original Dotīs are still working in the bios. it seem to be a intel application to create your own bios....
the bios can be modified,but we still donīt know how.that work was done by a spanish company called "prodigios" .they modified all the dots that subastaspc.com are selling but they donīt give us any information at the moment.
Subastaspc.com are ####in mother####ers,write to them if you want but probably you will get no answer.
after installing other OS we are modifing the hardware,installing capture cards external IDE cd roms etc... my aol has many holes in the chasis to get out the wires...
Sorry for my ####ty english dudes
