[Phoenix Bios Editor 2.2 12
Cherrie Patete
@coromonadalix - What OS is used here, win8-10? If you remove main HDD, do you then get boot selection screen, or gain BIOS entry?
Please upload copy of the BIOS you made, I will check and see if anything I notice that can be done.
Well paid for an bios file at : -aec-6822-bios.html?highlight=aec
File is not the same size ? not sur if its a zip or do i have to rename it, tried with modbin and cbrom to list bios modules and doesnt work
oh just received 2 files thru skype with the seller ill pm you later have to go work
they are 4mb in size each ??? and rom extension
version 10 and 13 ???
A822AM10.rom
A822AM13.rom
ill sent you private link later
thks
The application for Windows Phoenix BIOS Editor has an easy interface for modifying PhoenixBIOS 4.0 Rel. 6 and then there will be no need to reinstall the BIOS later.
It supports unpacking, replacing, and repacking of components within a BIOS image, and allows changing of settings and modifies the application to the actual BIOS itself.
Verified version Phoenix BIOS Editor

I searched all over the Internet to find this program with the least number of threats, if in doubt, you can see for yourself.
The board came with an AMD X5-133 installed. I had a board with the same chipset and the same CPU back in '96. So I want to recreate my old setup. I was able to get it running @160MHz again after hacking the VRM to 3.6V. 15ns cache is also installed and working.
The other thing I suspect are pretty bad memory/cache timings. The Phoenix Bios on this machine has no options at all. Once I have the riser card I'll try Award bios images for other boards with the same chipset. Hopefully I can mod those to include the VGA bios. I have little hope for the on board audio though. Until then, I thought I'd try my luck here. Maybe you guys have some ideas.
- did anyone here have any luck with extracting/hacking an early Phoenix Bios? I tried various cbrom versions without luck.
- are there maybe any chipset specific tools to set mem/cache timings in nvram from DOS?
Afaik, editing early phoenix is diving into the unknown. While AMI and Award do have utilities like AMIBCP and Modbin/Cbrom that generally let you modify the bios, i don't know of any such utility for 4.0x phoenix. Maybe it does exist but i don't know about it or nobody has a copy of it anymore.
Using Cbrom won't work as that was always meant for award, and this bios is long before phoenix acquired award. As for chipset specific tools, those may exist but i'm not much of an expert in that type of stuff so i wouldn't know.
I've looked at PhoenixBIOS 4.x before. Portions of it are compressed. Compressed blocks start with a header containing the magic number 42 43 D6 F1 followed by two unknown bytes, a flag byte, a header length byte, a destination segment word, an uncompressed length dword, and a compressed length dword. What follows is compressed data. Yours uses LZARI compression from the Haruhiko Okumura set of sample LZ compressors published in 1989. Mine was a bit older and used LZSS.
The setup program appears to be in the second compressed block. I see signs of a cache speed 3-2-2-2/3-1-1-1/2-2-2-2/2-1-1-1, and ES1688 enabled/IRQ/DMA/I/O. Do you not see these settings in one of the tabs of setup? I don't think PhoenixBIOSes tend to have a ton of hidden options like AMI and Award do. You could also try explicitly restoring defaults which can change hidden settings.
The 8881/8886 have no public datasheets; the only source of information about them is the BIOSes and drivers. So you won't find much in the way of tweaking utilities. The 8886AF has some features to speed up IDE transfers that are not standardized and only activated when you install the UMC drivers.
Hey so much feedback ? It turned out the RAM and L2 timings are accessible in device specific config registers of the UM8881 PCI device. I wrote a little DOS prog today to read them. RAM was set to 1 WS read and 3 (!) WS write. L2 was set to 3-2-2-2 as expected. I fiddled with writing to these registers to turn off L2 for a start, but I had no success. I'm pretty sure it is possible to control timings this way but I have too little experience. I found a bare file "UM881.CFG" somewhere in the net that had the necessary register info. I only figured out later that it belongs to the free "ctchip34" tool distro, which probably can do these timing changes already. I have to try that.
But a couple hours ago the riser card arrived anyway. I flashed the Octek HIPPO 15 096017 bios. As expected, onboard video and sound stopped working, but otherwise this bios runs beautifully. Timedemo is back at 16.1 (from 12.9) and 3DBench sits at >90 (awful 52 before). Here is some Speedsys for you:
Now I want to try to add the GD5430 option ROM into the bios. And I can try to add additional cache sockets for 256k of L2. There's a bunch of unpopulated jumpers that are obviously related to the L2 cache.
Using Cbrom won't work as that was always meant for award, and this bios is long before phoenix acquired award. As for chipset specific tools, those may exist but i'm not much of an expert in that type of stuff so i wouldn't know.
I had an ATI Mach64 back then, specifically for the YUV video acceleration. Thats what I'm planning to put in given I can find the card in my pile. I still have the two VideoCD discs I bought in '95 on an Amiga fair in Cologne to view on this setup (Total Recall and Star Trek 2). I remember I ran some software MPEG decoder on Windows 3.1 before I switched to 95.
The first block has the CL-5430 VGA option rom., albeit with a strange header. Now if I manage to add that VGA ROM to the Award bios, will it still auto detect an external VGA adapter? The old Phoenix bios supported external VGA cards. It must have had some code that copied the internal VGA rom to 0xC000 only in the case there is no external adapter. I would expect that Award also supports this.
