What steps will reproduce the problem?
Attiny84 running on 8 MHZ fuses: high= DF, low= E2 and ext= FE
bootloader recompiled for 8 mhz, and remapped the pins for the LED and serial. 
Serial baud is still on 9600

Led blinks 3 times on powerup. 
arduino 0019 on winxp fails to upload.
arduino error:
avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64
avrdude: failed to write flash memory, rc=-4
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
Im using the autoreset. When arduino want to upload, its is reset twice (2 
times blink 3 times) when i see the TX/RX led flashing alot, like it should go 
normal. Then i get this error.

After the failed upload if reset the attiny, the led flashing 3 times again
