Hi all


It is possible to rewrite the chip bios , with Win XP, with Electronic
card, attacched to serial port, or parallel or Usb port?

Thanks

Regards

Presuming that the PC in question supports BIOS updates, yes it would be
possible over USB. BIOS updates are often delivered in the form of
executable files, so running the file from a USB-connected device should
be do-able.

Serial port? Yes, using a file transfer protocol to download a BIOS
update and then run the update. Parallel? Not supported in a standard
setup. Either could be used if an appropriate application was running on
the target machine.

I mean

through an electronic card, with which to connect the chip bios,
rewrite the file bios.rom, in to plcc bios chip, using software, and
the electronic card, connected to the serial port or usb port.

Are you looking for something to program a PLCC flash chip that contains
a BIOS, with the chip removed from the parent system?

If so, do a search for "device programmer." Some examples are
<http://www.conitec.com/english/galep4.php>
<http://www.xeltek.com/SuperPro-M-product-17713>
<http://www.tequipment.net/BK844USB.html>

New ones are not cheap, so searching the auction sites for a good used
model may be indicated.

There used to be a fair number of hobby/enthusiast models out there but
that market has pretty much dried up with the advent of JTAG and other
serial in-system programming.

Sure, but It's probably cheaper to order a replacement bios chip from the maker.

What boots Slackware?

It certainly is NOT. The BIOS is a separately licensed software
component, after all; delivering a second chip costs the maker
another license fee, while supporting an update path simply
debugs the original version, under the original already-paid-for
license.

From a cold boot, the ROM BIOS reads the boot sector of the floppy,
the CD, or the HD. That points to LILO, the Linux Loader, which gives
me the option to boot Slack or Windoze. If I pick Windoze, then LILO
passes control to the windows loader, and if I pick Slackware, then
LILO goes ahead and starts the Slack boot procedure on the drive. The
first thing that the loader does is read the new BIOS, and reports the
data check, and then runs init, and so on.

A quick google turned this up - they can probably explain it better
than I can:

Hope This Helps!

Or, the gag answer, of course, is "the reset button" ;-)

A-HAH! It doesn't bypass the ROM entirely, now does it?

No need. You admitted your mistake already.

I picked a brand at random and did a search...

$5-30

cheaper than any commercial JTAG or I2C programmers I've seen.

Yes, that's a good price. It isn't a 'replacement part', though, it's a
reprogramming service, you have to detach and send the old BIOS chip to
them. No multiple-copies-of-the-licensed-software issues there.
