Actually, the use of EPROM puzzles me. I think no one makes new UV EPROMs, only OTP EPROMs. Flash ROMs are being manufactured, and quite inexpensive (e.g. SST39SF010A), older no longer manufactured Flash ROMs are also cheaply available. Hi, Serge! Thank you for your reply. I will convey your …

Book8088 BIOS v1.0.5 You should consider making pull requests to the main repo at least for the features you think are more mature and stable while keeping your repo and releases for the more experimental stuff. For example it would be nice to have floppy emulation merged into main It's not …

So. After writing code that works absolutely good in PCem, but not on Book After being pointed by Krille to a XTCF include. Figuring out that XT-CF ports are shifted up by one bit Finding out that card is in 16 bit mode on start and should be switched to 8bit PIO ... First proof of CF card access …

Hi. It should just work if a program supports it. Try Super Solvers Adventure for example.

And a question. Any ideas what problem on ISA bus could lead to this problem? (see photo, EGA on ISA extender) EGA card works perfect on Pentium, on Book8088 it gives memory error (beeps) and shows that kind of picture. EGA BIOS makes three-pass REP STOSW with different pattern fill or video RAM and …

Found small boards, called "SOIC to DIP adapter" here. Redone DMA hack, and finally put Waveshare Zero Keyboard Adapter 😀 to a ribbon cable. 5V, Ground and Int lines are now more sturdy AWG30 wire. Still waiting for kbd chip and V2 Book to arrive.

I'm no expect, but that looks like textures missing. Is your card AGP or PCI? I might guess AGP and something related to AGP transfers.

Now about overclocking. I lauched V.Control and noticed that my new default memory clock now is 110Mhz :) I tried to set "Default" and card hangs(!) So BIOS sees that one chip is off (5ns) and does some adjustments. That's cool, really. Setting clock to 124/124 makes Quake hang in about 10 mins. 100 …

Thanks guys! I'm very happy myself - and i'm no more afraid of microsoldering. Modern fluxes are miracle. As for overclocking - i didn't, but i'll try :) This card replaced my fully dead (killed by own power convertor) Rush in P200MMX PC, so i think bottleneck will be CPU, not the Banshee. …
