Postby Weller500 » Tue Mar 18, 2014 5:31 pm

Hi guys

I´ve an old Pc chash System from manufacturer Omron.
The Pc was not Produced from Omron only ,it´s from Manufacturer Trigem
Model TG7701. An old Pc with IDT-C6 Winchip 200Mhz CPU and 256 MB Ram. The old hdd was chrashed (8 .1 GB ide ) and i´ve not found the same new one. Must be changed an new one with 80 GB (found no smaller ). The Bios was from 1997 Ami Megatrend´s an the Number 51-3317-04698-001101111-071595-SiS5597-H .On board was an SIS Chip and audio was an chrsytal audio chip. Contact with Omron ,they says another company use the support for this PC but this support not answer (Torex Germany). Any Ideas to found an newer Bios for this Mainboard ?
The old bios detect my new hdd as 8.1 Gb and the rest ( over 70 Gb) was not working.

That would be the
Midas: http://www.elhvb.com/mboards/trigem/pro ... D_base.htm
or Woodland+: http://www.elhvb.com/mboards/trigem/pro ... B_base.htm

You might get 32GB out of that disk by setting the capacity limit jumper but not more since the AMI core of that bios cannot handle it. No bios update/upgrade is going to change that.

I would love to have an actual picture of that board as to identify it properly.

Here is a link to SIS 55xx model chipsets and BIOS types.. plus mobo providers.. http://www.wimsbios.com/chipset/2A5II.jsp
Probably no success in finding a newer BIOS than what is had. The BIOS has to be tailored to the mobo design, a different one likely won't work.
And as to hard drives, getting a really new drive of less than 100 GB is not easy. You may find some laptop hard drives of less than 100 GB, and they should work with the system if an adapter to standard IDE is used. Set the primary partition to no more than 8 GB, and create an extended partition. In that, you could go around 10 GB each additional drive partition, and it should work. But with only 256 MB system memory, you could not use newer than Win XP as an OS. A Linux system would be more compatible.
In checking my archives, I found nothing newer than what you have for a BIOS.
F@H.. to solve mankind's maladies.. in our lifetimes!

Is the PCI slot already taken? Otherwise you may consider using a bootable harddisk controller interface card. They usually can handle larger disks (you need LBA48 support). Something like this:
