(eepro100b flashing instructions) :-) -Date: Sun, 23 Jan 2000 01:53:08 -0500 -x-sender: mdc%thinguin.org@cdi.entity.com -x-mailer: Claris Emailer 2.0v3, January 22, 1998 -From: Marty Connor <mdc@thinguin.org> -To: "Netboot List" <netboot@baghira.han.de> -Mime-Version: 1.0 -Content-Type: text/plain; charset="US-ASCII" -Message-ID: <1263512144-341319205@entity.com> - -Continuing the Etherboot World Domination theme, I noticed that there was -a PCI ethernet card on my bookshelf that still contained the original -vendor's code in its flash memory. The card virtually cried out to be -flashed with Etherboot 4.4.1. :-) - -After having figured out how to flash the 3C905C last week, and owing to -the fact that the temperature here in Cambridge, Massachusetts (USA) has -dropped well below freezing, I decided to explore the possibility of -flashing the Intel eepro100b that was sitting on my bookcase. - -After determining that it was unlikely that one could flash the chip in -user mode under linux like the 3C509C, I turned to other options. (the -reason is that the flash is memory mapped to a place that causes a core -dump if accessed. i suppose one could to patch the kernel to flash the -card, or add a linux device driver, but... :-) - -By the way, If you are ever looking for Linux utilities for Ethernet -cards, you may want to check out: - - http://cesdis.gsfc.nasa.gov/linux/diag/ - -which is a treasure trove of tools for manipulating and testing Ethernet -cards, all with source, courtesy of Donald Becker. - -At this point, I felt it was time to make a virtual trip to the Intel -site (http://www.intel.com/), and search for utilities that might work -with the eepro100B. I found two candidates: FUTIL and FBOOT. I -downloaded, decompressed, and transferred them to a DOS formatted floppy. -Next I determined (after a few tries) that F8 will let me get to DOS -instead of booting windows. (I tend to avoid Windows when I can). - -I first tried FUTIL.EXE. No good. It told me it didn't recognize the -flash on my eepro100B. how unfortunate. and I had such hopes :-) - -Next I tested FBOOT.EXE (available at -http://support.intel.com/support/network/adapter/pro100/100PBOOT.htm) -This program did in fact recognize my eepro100b card. - -The thing about FBOOT however, is that it thinks it only can load certain -files. I of course needed to load an Etherboot image. It appeared to -have no option for doing that. Things looked grim. - -Then I noticed that FBOOT was kind enough to do the following dialog: - - Select Option (U)pdate or (R)estore: U - -I chose Update and it then offered to back up my flash rom for later -restore: - - Create Restore Image (Y)es or (N)o: Y - -I chose "Y" and it proceeded to write a file of my flash memory, which -contained the Intel code. - - Writing FLASH image to file... 100% - -It then erased the device: - - Erasing FLASH Device... 100% - -and then programmed it with fresh code (stored inside the program, no -doubt): - - Programming FLASH Device... 100% - -So now I had a backup of the Intel boot code in a file strangely called: - - 2794FC60.FLS - -Hmmmm, interesting name. The MAC address of the card is 09902794FC60. -They just name the file with the last 4 octets of the MAC address and -.FLS. The file is exactly 65536 bytes, which would make sense for a 64K -Flash Memory device. - -Then I got to thinking, I wonder how carefully the "restore" part of -FBOOT looks at what it is loading? What if I took an Etherboot .rom -file, padded it with 48K of 0xFFs and named it 2794FC60.FLS. What if I -then told FBOOT.EXE to "restore" that? - -Well, I guess by now, you know it worked :-) - -The card came up with the delightful Etherboot banner, Did DHCP, tftp, -and started a kernel. - -The only unfortunate part is that you need to do this under DOS because -you seem to need to be in real mode to program the card. Oh well, -sacrifices have to be made :-) - -So, in summary, to prepare Etherboot image for flashing into the Intel -EEPRO100B card with FBOOT, you need to first make an eepro100.rom file, -as usual. - -Then, see how large it is, with an "ls -l eepro100.rom". the answer will -probably be 16,384. You need to pad it with hex FFs to make it 64K for -FBOOT. I used the following two lines to create the flash image file. - - $ perl -e 'print "\xFF" x 49152' > 48kpad.bin - $ cat eepro100.rom 48kpad.bin > 2794FC60.FLS - -Next write it to a DOS Floppy: - - $ mount -t msdos /dev/fd0 /mnt/floppy - $ cp 2794FC60.FLS /mnt/floppy - $ umount /mnt/floppy - -Now you need to get to DOS. You could actually use a bootable DOS floppy -with FBOOT.EXE and 2794FC60.FLS on it. I started a Windows box and hit -F8 right before Windows started, and chose option 5, "Command Prompt -Only", which gives you DOS. This program can't run in a DOS window under -Windows or anything like that. You need to be in real DOS. - -Next it's time to run FBOOT. It will detect your ethernet card(s), ask -you which one you want to program, and let you choose it from a menu. - -now the fun part: - - Select Option (U)pdate or (R)estore: R - Erasing FLASH Device... 100% - Writing FLASH image from file... 100% - -Time to reboot and let Etherboot take over. - -So there you go, a way to make Intel EEPRO100Bs play nicely with -Etherboot. Maybe we should put these instructions in the Etherboot -contrib directory so people who have eepro100b cards will be able to -avoid 3C905C envy :-) - -I hope this helps a few people out. - -Regards, - -Marty - ---- - Name: Martin D.
