Thanks for the ratings.
Catalyst 3750 or 3560 switches with a 16-MB flash memory can experience problems due to flash memory constraints, especially if they are using larger size images, such as c3750-ipservicesk9-tar, c3560-ipservicesk9-tar, c3750-ipbasek9-tar, or c3750-ipbasek9-tar images. These are the affected switches:
Catalyst 3560: WS-C3560-24PS and WS-C3560-48PS
Catalyst3750: WS-C3750-24PS, WS-C3750-24TS, WS-C3750-48PS, WS-C3750-48TS, WS-3750G-24T, WS-C3750G-12S, WS-C3750G-24TS, WS-C3750G-16TD
The workaround for these switches is to use the corresponding lm images, such as the c3750-ipserviceslmk9-tar or c3560-ipserviceslmk9-tar images, which require less memory. In future releases, images are expected to grow more in size, requiring more need for the lm images.

Yes. This is a new kind. The "l" simply means "lite", filesize wise. The IOS BIN file is the same but the HTML files have been cut down to fit into a 3560/3750 with 16 mb flash.

Long time ago i boot 2500 router directly from tftp, because ios image was bigger than flash on 2500 router and it works fine!
I try to find the way to do this on Cat3750.
If you say 3750E or 3750X there's another way to boot: USB

Thanks for help!
Now i think there is no way to directly boot Cat3750 (not E and not X) from tftp.

The 3750E can boot from TFTP
Ethernet cable in the MGMT Ethernet port.
Set Variables in ROMMON
IP_ADDR=x.x.x.x/m.m.m.m.m
DEFAULT_ROUTER=x.x.x.x
boot tftp://x.x.x.x/bootfile.bin
