Hi there,
we just tried to install RouterOS on a 512MB CF Card. The netinstall utility finished the installation but the Router didnt boot. The SYSLINUX was startet and then we got a "boot failed" message.
We tried two different 512MB Cards, two different PC's (from where we wrote the image) but it didnt work.
Then we tried a 256MB CF Card and it works.
Is there a problem with cards > 256MB?
Thanks in advance.
HI stenSome of the sandisk 512 MB CF cards have DMA issues.
64 MB Biwin cards are incredible when they are fixed.
this is a very bad news. It means also sandisk could have a bad behaviour? What memory do you suggest? please can you tell me the exact model/part number you are using with wrap/routerboard?
Thank you
Well there were a whole bunch that had bad firmware.When fixed?64 MB Biwin cards are incredible when they are fixed.
You could ask the people you got them from, to downgrade the firmwares and at the same time disable DMA access.
I have the firmware but i have to verify if i am allowed to help you.
Hmmm
Im trying to run Mikrotik 2.9.39 on my CF-IDE 512MB Dane-Elec flashdisk again.
- I installed using a USB Cardreader and the netinstall utlity
- Placed the CF in my MT ( no boot)
- Changed Bios harddisk mode settings from auto to normal and boot was fine
- Changed Bios harddisk mode setting from normal to auto and boot was still fine
- Changed Bios harddisk mode setting from auto to LBA and boot was still fine
Im not sure whats happening and what to do.
MT Running on a ASUS P2B-S Bios version 1013 (old system)
The CF Found as Toshiba THNCF512MPG Using LBA mode 4
The BIOS says:
Note some OSes (like SCO-Unix must use "normal" for installation)
And everytime i placed an new install on the CF-Card there is a bootfaillure reported. So i must switch to Normal mode instaid of Auto (LBA) the first boot
And the solution use a CF-IDE 256MB Dane-Elec flashcard
This wil be Found as Toshiba THNCF256MMA using LBA mode 2 and with this card the first boot is working fine
So it seems that the LBA mode 4 is messing with the linux bootloader because the LBA mode 2 is working fine
Using RouterOS Beta 5 still give problems
Can you MT Guys fix this, and mayby translate it to good english and make it a sticky ??

Dude, that's just common sense!
Are you confusing LBA with DMA?
If you still mean LBA:
Running it in normal mode is just common sense for anything smaller than a 540 mb harddrive. LBA mode is to overcome the problems faced when computers got bigger harddrives (around 540mbyte). Enabling it will result in less storage capacity and different disk layout.
If you meant DMA:
If so, then there is no reason to take it above 16bit (word size) DMA 2.
The higher the performance then the higher probability of errors. Harddrive *IO performance* will not affect your routers ability to forward packets but an harddrive *error* will affect your routers ability to function.
If you are still confused then feel free to read up on the subjects. Maybe you could correct me if i'm wrong as well?
