Hello 9fans,
I heard many ideas in this thread, but I don't hear comment for my offer:
RS> How about external FlashROM (24c01 - 128 bytes, 24c02 - 256 bytes
RS> and 24c04 - 512 bytes) on LPT (or COM) port through i2c bus. It's
RS> more easy and most standardised.
I2C very easy bus and can be attached to LPT, COM or anything else
(i2c controller integrated in system board). In this way you need:
1. 24c01(02, 03) IC (manufacturer Atmel or other)
2. 4 wires (SDA, SCL, plus, minus)
3. LPT connector
4. maybe 2-3 diodes
5. Cold head, hot heart and direct hands :-)
IC can be powered form LPT, COM, Game port or direct from PC.
Disk emulation (CF-IDE and other), usbflash it's very $$$ way!
Additional floppy or HDD, but why we use PXE.
New idea: create special nvram driver with parameter setted while
compilation. This is bad idea, this my opinion, but costless.
I wont see comment.
Sergey.
