I was tracking down a new bios for this board myself after I was trying out a new one and lost the old one (1.10a) that was on it. (being stupid I know) It was one hell of a quest, but I found a more recent bios for the M5SIB board. I'd rather not anyone else have to go through what I did to find it, given that the board was used and called many other names from PB and the like. I have loaded and tested the bios in my own board and it works like a champ. I can't attest to what size drive it will handle, as I don't have any drive larger than a 20GB. But this new bios is for me more stable than the previous bios that I had which was referred to as version 1.10 Now the version that I have is the 'b' version 1.10 This time it doesn't state that in the bios screen like it did with my 'a' version, but the date does reflect the update, dated 10/12/99 as it also does on the bin file. I believe this is a PB bios (the exe file name refers to the 992 PB mobo) as it has a logo file on the disk, but I am not positive, since I bypassed straight to the award flash program. I couldn't stand having the PB logo up there with the last bios. Since I did find this bios on a hunch (PB and thier multiple name schemes!
No wonder they ran and hid in europe!) because of a tip I read here, I wish to return the favor here as well. Feel free to e-mail me to get a copy if you'd like. madcat@aselabs.com BTW-This newer bios has turned out to be surprisingly strong overclocker. The K6-2 300 I have been using in it would only stay stable at no more than 375Mhz. It is now clocked and holding very stable at 413Mhz (5.5 x 75fsb) I'll try getting it stable at 415 using the 83fsb speed. There is a jumper combo that will enable an 83Mhz fsb on this board.(pcb ver. 2.0 anyways) Cheers!
How is the re-write for the BIOS on the Packard Bell BIOSTAR Pegease M5SIB Board doing?
The biostar mother archetiture I think was onlyl suppose to handle up to Windows 98. The tag on the packard bell machine said "Designed only for Windows 98." Me not believing, I tried to install it only. XP and Win2kPro will not install on this board.

It has been apparent to me that I need an ethernet connection, but in order to do so I need to free up one of the PCI slots.
Right now, it has a Pci video card, a modem, and the Pci adapter card. So, in the coming months, I will be refreshing my memory on how to backup an existing bios. Also, I must find my original documentation for this machine. I wasn’t sure if the bios chip in this biostar board is flash-able, but with the help from biostar support I think I will be ok.
I may plan to reclaim some of the lost space on the two drives on this board. Swapping the drives will depend if the bios upgrade is successful. If I still cannot upgrade the bios, then I have to image the 40 gig drive using only 10 gigs to an 20 gig drive. The 40 gig drive can go into another machine I was planning on building. Stay tuned as I decide and gather the parts I need to getting a free pci slot open. It is going to be a long grueling process.
