Hmm...I think I tested it on the MiSTeR, but I can't remember tbh I have little time as of late, so it's in the queue along with a small surprise feature that would complete this project. But its going to be a while before I have some spare time to implement it. If you find a chance to test it on …

Well if it can't be solved it's no big deal for me at this point. The system is completely usable with the ACPI tables removed. The shutdown bug is nothing more than a mild annoyance. Good to know. Currently, I wouldn't know what to do except for inserting debug outputs at various places and …

To get this thread back on track - I can report there is no observable difference between p3bf_no_acpi_tables and p3bf_no_ACPI_tables_no_A0_A1_handlers. Both builds allow Win2k setup and Acronis True Image 2011 to load without issue, but both also suffer from the same shutdown bug. I have also …

I apologize that I start with a post off topic.... I'm playing with an ASUS P3V133 trying to get a 16bit ISA controller to work(CA9342 no BIOS no PNP) the disk attached is detected by the mainboard but cannot be accessed, I would like to understand if there is hope to make it work or if because of …

BTW, I remember one more potential PPRo HW incompatibility problem. PPRo has CMOS signal level 3.3V, but Pentium2/3 have 2.5V CMOS levels. Sometimes some PPRo->Slot1 converters have pull-up resistors to 3.3V for CMOS signals. In some boards PPro may not starting (or stop during POST) even with right …

Thank you, that is interesting! I've taken a quick look. On a first glance at the 0102 BIOS, I can't find any positions where the code actually reads anything from port 0xB2. Maybe the handlers are still missing there? Yes, very probably that no the port 0xB2 reading in BIOS code, since that BIOS …

Thanks a lot for your work and the documentation! The MSR stuff was straightforward enough to find out, but having no Pentium Pro hardware at hand, I probably would not have located the APMC write problem. Thank you also! You are doing a very helpful job!! Good to know. Do you happen to remember …

There is no Pentium Pro to Slot 1 adapter left anywhere on sale at, eBay, Aliexpress, Newegg, Amazon etc. The Pentium Pro adapter can only be used with 66 MHz bus. Not all mainboards can support this fsb, like i815 and i820 chipset. The performance of Pentium Pro is up to 233 MHz with of the die …

Well, it doesn't work unfortunately. But I found an old Russian article about running a ppro in a 440bx board, so I'll have a read. Really appreciate your help bud/maam!!

Thanks! Your board has not chipset, only standard peripheral ICs. I guess, it might be repaired, needs oscilloscope and soldering equipment.

Perhaps TLV_V220 will work with a certain jumper setting jp7 jp8 jp9. In my case, jp8 - includes access to UMB .jp7 - the address is selected from e000 - efff or d000-dfff. Jp9 - the use of memory modules 1024kb. Maybe you have other options. Try to use all the memory slots sipp and dip together. …

I tried out TLV_V220. As expected, it doesn't work on my board, since chipset is unsuported. CHIPSET.EXE just stops my machine. I found that turbo mode is switched (not minus!). So, first pressing - turbo is disabled; second pressing - turbo is enabled and etc. do nothing. I apologize for invalid …

Thanks! Seems it is variant of UMB driver, for extension DOS RAM. ACC Micro is supportred for 286 machine, non 8088. But I'll try it during next days.

EMS driver is specific for each hardware, it is not universal. Big chances, that our boards do not support EMS at all, additional memory maybe only for specific purposes, likely known cdisk.sys for JUKO XT. HIMEM.SYS is XMS driver, only for 286+ machines (it used CPU features for memory manage). …

EMS is just a specfication, the memory can be located anywhere, even on a separate computer device (->EMS card, swap file, another PC via serial cable). ;) Yes, I apologize. But EMS locations in non-UMB area, since a lot of adresses in it reserved for expansion ROM, VGA memory, EMS window and BIOS. …

denis74 , I afraid that hiram just UMB manager, it is not EMS. And it doesn't use specific hardware that locations on our boards. UMB manager potentially might produced more problems than fixed it, especially if your have a lot of cards with expansion ROM. Genuine EMS memory must be locations above …

Many thanks for BIOS image! Your BIOS is located in the last 8KB of image and different from my BIOS. My board equips Phoenix BIOS. Keys Ctrl+Alt +/- do not switch speed mode in my board. But speed always switchs to non-tuirbo mode after start CHECKIT memory test! I'll try make additional photos …
