Bug Description

*****************************************************************************
NOTE: Please update your BIOS to get grub support for the Jmicron Chipset!

Look here: http://www.jmicron.com/FAQ_20330.htm

Q10: Can JMicron chip support linux/grub boot?
Ans: Yes , JMB bios 1.06.53 or above already supported.

*****************************************************************************

Binary package hint: grub

I have an Asus P5B motherboard with a PATA DVD drive and a SATA HDD, both of which are attached to the JMicron controller on the motherboard. I can get an Ubuntu Edgy daily (I last tried the 7th October build) to install but upon rebooting, Grub reports an error (error 21). I believe this is because Grub can not see the drive attached to the JMicron controller or the controlelr itself.

Once the ICH8 fix is released, I hope that channel on the motherboard will work instead, however people wishing to use the JMicron controller will still face the problem.

I confirm too. I have installed Edgy on a SATA drive connected to ICH8, but if I move it on Jmicron, I get grub error 21. (Well, ok, it's maybe a strange manipulation, but I think it should work?)

Same here. Msi neo p965.
w/ jmicron gives error 21.
w/ ich8 gives another error, since ich8 isn't fixed at the moment.
result: No system running at all.

This surely is a critical bug to be fixed...!
I wonder why this situation has not changed at all in such a long time.
I use LILO as my bootloader to boot ubuntu, but I would like to see GRUB working along with JMicron controllers.

I had same problem with P5B. I tried to install to PATA and SATA disks. PATA-drives were tested with different jumper settings, cable select/master/slave. I updated to newest beta bios version 0806 (2006/11/09 update) which solved the
problem.

Same problem with ASUS P5B series. Installed on PATA HDD (Primary) using PATA DVD/CD-RW (Secondary). Installs without a problem, but "Grub error 21" upon reboot.

Rebooting using Live CD, cannot find HDD in /media directory. Sysguard shows that both HDD and DVD/CD-RW are detected by system under the Jmicron controller, but not visible in /media.

Will try the BIOS upgrade shortly and report back.

OK, just tried with the latest BIOS update from ASUS, which incorporates an update to the JMicron controller's BIOS as well.

Ubuntu 6.10 installs and boots perfectly.
