Also binary smbmount won't work with 2.2.x, so you have to recompile with 2.2.x headers following Samba's readme. Yet even that won't guarantee reliable work untilsomebody fixes kernel's smbfs module.2.4.1. BOOTP, TFTP.There are number of BOOTP, TFTP servers for Windows on the market. You could find themhere:- www.walusoft.co.uk (Walusoft's tftp);- ftp.coast.net/simtel/nt/internet/tftpds12.zip (Millwood AB's tftp);- ftp.cabletron.com/pub/snmp/bootftp/boottft2.zip (Cabletron's bootp/tftp combo);- www.tellurian.au.com (Tellurian's bootp, tftp, dhcp servers).- www.metainfo.com (Metainfo's DHCP server)- www.nts.com (Network Telesystems's DHCP server in IPserver package)My choice was Tellurian's products - very reliable, simple to install, attractively priced(fully capable evaluation versions are available).2.5. Bootprom.Ken Yap's Etherboot <etherboot.sourceforge.net> will tell you everything about bootprom. Here I just want to mention that normally you would have to put bootprom's code into networkadapter's PROM. But if your hardware like mine has BIOS programmed in flash you could re-program it to add bootprom (some BIOS requires special programmer to do that, others don't)as BIOS extension.This is what I did to add ne.rom (bootprom generated by Etherboot's makerom for NE2000 clone) to AMI BIOS on my flash:- read flash content by programmer into bios.bin binary file;- use one of available binary editors (say www.simtel.net/Win95/editors/hxp3005.zip to add  ne.rom to bios.bin (and to edit ne.rom if necessary);- write new bios.bin back to flash.Notes:- makerom generates bootprom for standard EPROM sizes (8k, 16k, 32k, etc.), so if you tight on   space use -s flag to adjust size (or cut it manually to multiple of 512 bytes blocks, just  don't forget to adjust extension's length which is coded in Byte 2 and checksum to 8 bits   of zero;- valid absolute addresses for BIOS extensions are from 0xC8000 to 0xF4000 (check with   motherboard's manufacturer how flash is mapped onto system memory space);- Byte 0 must be 0x55, Byte 1 must be 0xAA, Byte 2 must be extension's length in 512 bytes   blocks;- extension BIOS has to start at a 2k boundary;3.
