I try this metod for netinstall ( i use before in anothers RB and i can fix but dont this time)

a) Disable Firewall
b) Connect PC to Port 1 on Mikrotik
c) Disable all other network interfaces on the PC - LAN, Wireless, Virtualbox
d) Set static IP of 192.168.88.3 subnet mask 255.255.255.0 gateway 192.168.88.1 on PC
e) Run NetInstall
f) Select “Net Booting”
g) Mark “Boot Serve Enabled”
h) Selected Client IP address of 192.168.88.1
i) Keep reset pressed while powering on
j) Keep holding the reset pin till a beep sounds. Release immediately
I get stucked in this step - Never show in netinstall and if i release RESET , the Router start to do the loop of beeps.



k) Router showed up in Netinstall’s list ()
l) Unmarked “Keep old configuration” and “Configure Script”
m) Unzipped “all_packages-mipsbe-6.5.zip”
n) Selected all packages by browsing to the unzipped directory and using the “Select All” button
o) Clicked on “Install”
p) The progress bar moved to 100% as the packages were uploaded (
)
q) The router rebooted - Beep once, some time later (1 min or so if I recollect) a second beep
