Here is one 3640 which just does it. It boots up image from flash and 
after that loads new IOS using TFTP

r1-Trt-KJ#sh ver
Cisco Internetwork Operating System Software 
IOS (tm) 3600 Software (C3640-JS-M), Version 12.2(15)T9,  RELEASE SOFTWARE (fc2)
/----/
ROM: System Bootstrap, Version 11.1(17)AA, EARLY DEPLOYMENT RELEASE SOFTWARE (fc2)
ROM: 3600 Software (C3640-I-M), Version 12.0(7)T,  RELEASE SOFTWARE (fc2)
/----/
System image file is "tftp://10.0.0.1/c3640-js-mz.122-15.T9.bin"
/----/
Configuration register is 0x102

r1-Trt-KJ#dir
Directory of flash:/

    1  -rw-     4703156              <no date>  c3640-i-mz.120-7.T.bin

r1-Trt-KJ#sh run
/----/
boot bootstrap flash:c3640-i-mz.120-7.T.bin
boot system tftp c3640-js-mz.122-15.T9.bin 10.0.0.2
boot system tftp c3640-js-mz.122-15.T9.bin 10.0.0.1
/----/

I put two TFTP servers not because to get backup but it takes so long for 
router and switch to set ethernet up that first one gets timeout every 
time. So, actually there is no TFTP server on 10.0.0.2, it just reserves 
some time to get everything up :-)
